A videocassette recorder ( VCR ) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other AV sources and can play back the recording after rewinding. The use of a VCR to record a television program to play back at a more convenient time is commonly referred to as time shifting . VCRs can also play back prerecorded tapes, which were widely available for purchase and rental starting in the 80s and 90s, most popularly in the VHS videocassette format. Blank tapes were sold to make recordings.

123-531: VCRs declined in popularity during the 2000s and in 2016, Funai Electric, the last remaining manufacturer, ceased production. The history of the videocassette recorder follows the history of videotape recording in general. Ampex introduced the quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commercially successful videotape recorder using two-inch (5.1 cm) wide tape. Due to its high price of US$ 50,000 (equivalent to $ 560,000 in 2023),

246-664: A 70 percent share of the market when it decided to pull the plug on the format in 2010. Sony still develops magnetic tape storage technologies along with IBM , and are one of only two manufacturers of Linear Tape-Open (LTO) cartridges. In 1998, Sony launched the Memory Stick format, the flash memory cards for use in Sony lines of digital cameras and portable music players. It has seen little support outside of Sony's own products, with Secure Digital cards (SD) commanding considerably greater popularity. Sony has made updates to

369-453: A Super Famicom with a built-in CD-ROM drive, named the "Play Station" (also known as SNES-CD ). However, a day after the announcement at CES, Nintendo announced that it would be breaking its partnership with Sony, opting to go with Philips instead but using the same technology. The deal was broken by Nintendo after they were unable to come to an agreement on how revenue would be split between

492-518: A built-in ATSC tuner, the HM-DT100U, but it remains extremely rare, and therefore expensive. In July 2016, Funai Electric, the last remaining manufacturer of VHS VCR/DVD combo recorders, announced it would cease production of VHS recorders by the end of the month. As a result of winning the format war over HD DVD , the new high definition optical disc format Blu-ray Disc was expected to replace

615-402: A cause of random dew sensor warnings. Usually, a "DEW" indicator or error code lights up on the display of most VCRs/camcorders, and on some, a buzzer may sound. Magnetic tapes could be mechanically damaged when ejected from the machine due to moisture or other problems. Rubber drive belts and rollers hardened with age, causing malfunctions. Around the late '90s and early 2000s, DVDs became

738-783: A completely separate financial entity owned by Sony, so as to retain the project and maintain relationships with Philips for the MMCD development project (which helped lead to the creation of the DVD ) In 2021, the WIPO 's annual review of the World Intellectual Property Indicators report ranked Sony's as ninth in the world for the number of patent applications published under the PCT System . 1,793 patent applications were published by Sony during 2020. This position

861-482: A continuous audio signal. While the video signal can easily hide the head-switching point in the invisible vertical retrace section of the signal, so that the exact switching point is not very important, the same is obviously not possible with a continuous audio signal that has no inaudible sections. Hi-Fi audio is thus dependent on a much more exact alignment of the head switching point than is required for non-HiFi VHS machines. Misalignments may lead to imperfect joining of

984-624: A department store building in the Nihonbashi area of Tokyo . The company started with a capital of ¥190,000 and a total of eight employees. On 7 May 1946, Ibuka was joined by Akio Morita to establish a company called Tokyo Tsushin Kogyo ( 東京通信工業 , Tōkyō Tsūshin Kōgyō , Tokyo Telecommunications Engineering Corporation) . The company built Japan's first tape recorder , called the Type-G. In 1958,

1107-406: A few for In-flight entertainment . The VR-1500 and VR-660 found service at educational institutions especially due to their relatively low cost vs. 2-inch (51 mm) quadruplex VTRs. These machines were simple to operate, reliable, small in size—and produced, for their time, very good video without the complexity of the larger and much more complex 2" Quad machines. In March 1967, Ampex introduced

1230-457: A focus on reducing the major losses from the television business. In February 2014, Sony announced the sale of its Vaio PC division to a new corporation owned by investment fund Japan Industrial Partners and spinning its TV division into its own corporation as to make it more nimble to turn the unit around from past losses totaling $ 7.8 billion over a decade. Later that month, they announced that they would be closing 20 stores. In April,

1353-513: A format war with DVD-Audio . Still, neither gained a major foothold with the general public. CDs had been preferred by consumers because of the ubiquitous presence of CD drives in consumer devices until the early 2000s when the iPod and streaming services became available. In 2015, Sony introduced LDAC , a proprietary audio coding technology which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbit/s at 32 bit/96 kHz. Sony also contributed it as part of

1476-552: A frame accurate timing computer that enabled frame-accurate cuts and dissolve transitions by way of a two-input video switcher. Slow-motion sequences could likewise be programmed and could be "triggered" to begin via an external control pulse such as might come from an external VTR editor like the Ampex VR-2000 VTR with Editec. The HS-200 was the first system capable of single-frame video animation recording, using magnetic discs as opposed to videotape. The HS-200 also provided

1599-513: A high-fidelity movie sound system using sound magnetically recorded on the film itself, as contrasted with the technology of the time, which used magnetic tracks on a separate celluloid base film (later commonly known as mag stock). The result of this development was the CinemaScope / Todd-AO motion picture sound system, which was first used in movies such as The Robe (1953) in 35mm and Oklahoma (1955) in 70mm (and also in 35mm). In 1960,

1722-693: A home recorder, whereas rental cassettes could not be rewound, and had to be returned to the retailer in order to be rewound. Sony demonstrated a videocassette prototype in October 1969, then set it aside to work out an industry standard by March 1970 with seven fellow manufacturers. The result, the Sony U-matic system, introduced in Tokyo in September 1971, was the world's first commercial videocassette format. Its cartridges, resembling larger versions of

1845-452: A huge impact on developments the whole video signal chain. They did rebadge some specialist low-volume OEM products to complete the package, but their in-house teams developed industry leading products in the following categories: ADO – Ampex Digital Optics provided comprehensive frame manipulation in 2 and 3 dimensions. Adjusting the aspect, size, and rotation of the image was performed continuously in real-time. An optional digital 'combiner'

1968-465: A laboratory and hub for the company's line of industrial control systems, cyber security products and services and its artificial intelligence / machine learning technology. Ampex's first great success was a line of reel-to-reel tape recorders developed from the German wartime Magnetophon system at the behest of Bing Crosby . Ampex quickly became a leader in audio tape technology, developing many of

2091-409: A major income source. The video cassette recorder is sensitive to changes in temperature and humidity. If the machine (or tape) was moved from a hot to a colder environment there could be condensation of moisture on the internal parts, such as the rotating video head drum. Some later models were equipped with a dew warning which would prevent operation in this case, but it could not detect moisture on

2214-480: A name such as Sony Electronic Industries, or Sony Teletech. Akio Morita was firm, however, as he did not want the company name tied to any particular industry. Eventually, both Ibuka and Mitsui Bank's chairman gave their approval. According to Schiffer, Sony's TR-63 radio "cracked open the U.S. market and launched the new industry of consumer microelectronics." By the mid-1950s, American teens had begun buying portable transistor radios in huge numbers, helping to propel

2337-667: A part of any traditional keiretsu , Sony has a weak tie to the Sumitomo Mitsui Financial Group (SMFG), which traces its roots to the Mitsui zaibatsu . This connection dates back to the 1950s when it was the only bank the company dealt with. Sony is listed on the Tokyo Stock Exchange (in which it is a constituent of the Nikkei 225 and TOPIX Core30 indeces) with an additional listing in

2460-503: A readout with specific frame numbers showing from the 900 frames available (NTSC version). Sequences could be triggered to start from any of these 900 frames with frame-accurate repeatability for creative fine tuning of sequence start and end points. 1 inch type A videotape (designated Type A by the Society of Motion Picture and Television Engineers, SMPTE ) was an open-reel helical scan videotape format developed by Ampex in 1965, one of

2583-731: A slogan known as "make.believe" in 2009. Despite some successes, the company faced continued struggles in the mid- to late-2000s. In 2012, Kazuo Hirai was promoted to president and CEO, replacing Stringer. Shortly thereafter, Hirai outlined his company-wide initiative, named "One Sony" to revive Sony from years of financial losses and bureaucratic management structure, which proved difficult for former CEO Stringer to accomplish, partly due to differences in business culture and native languages between Stringer and some of Sony's Japanese divisions and subsidiaries. Hirai outlined three major areas of focus for Sony's electronics business, which include imaging technology, gaming and mobile technology, as well as

2706-650: A spinning head and relatively slow-moving tape. In early 1956, a team produced the first videotape recorder. A young, 19-year-old engineer Ray Dolby was also part of the team. Ampex demonstrated the VR-1000 , which was the first of Ampex's line of 2-inch Quadruplex videotape recorders on April 14, 1956, at the National Association of Radio and Television Broadcasters in Chicago. The first magnetically recorded time-delayed television network program using

2829-484: A total of 12 Emmys for its technical video achievements. In 1959, Richard Nixon , then Vice President, and Nikita Khrushchev held discussions at the Moscow Trade Fair, which became known as the " Kitchen Debate " because they were mostly held in the kitchen of a suburban model house. These discussions were recorded on an Ampex color videotape recorder, and during the debate Nixon pointed this out as one of

2952-482: A trip to Radio Frankfurt. The device produced much better fidelity than shellac records. The technological processes in tape recording and equipment developed by German companies before and during the 1939–1945 war were subject to patents which were effectively voided after Germany's 1945 surrender and defeat. Mullin acquired two Magnetophon recorders and 50 reels of BASF Type L tape, and brought them to America, where he produced modified versions. He demonstrated them to

3075-570: A wholly owned subsidiary through a takeover bid. On 1 April 2021, Sony Corporation was renamed Sony Group Corporation. On the same day, Sony Mobile Communications Inc. absorbed Sony Electronics Corporation, Sony Imaging Products & Solutions Inc., and Sony Home Entertainment & Sound Products Inc. and changed its trade name to Sony Corporation. Sony has historically been notable for creating its own in-house standards for new recording and storage technologies, instead of adopting those of other manufacturers and standards bodies, while its success in

3198-787: Is 54 °C (129 °F) and a typical time is 16 hours") to attempt to recover such tapes, allowing them to be played once more and the recordings transferred to new media. The problems have been reported on tapes of type 406/407, 456/457, 2020/373. Ampex Records was started in 1970. Its biggest hit was "We Gotta Get You A Woman" by Todd Rundgren (as "Runt"), reaching No. 20 on the Billboard Hot 100 chart in 1970. Ampex also originated three subsidiary labels: Bearsville , Big Tree , and Lizard. Ampex Records ceased operations around 1973; Bearsville and Big Tree switched distribution respectively to Warner Bros. Records and Bell Records , and Lizard became an independent entity. Later on, Big Tree

3321-520: Is a digital video tape format created by Ampex and other manufacturers (through a standards group of SMPTE) and introduced at the 1988 NAB ( National Association of Broadcasters ) convention as a lower-cost alternative to the D-1 format. Like D-1, D-2 video is uncompressed; however, it saves bandwidth and other costs by sampling a fully encoded NTSC or PAL composite video signal, and storing it directly to magnetic tape, rather than sampling component video. This

3444-621: Is an American electronics company founded in 1944 by Alexander M. Poniatoff as a spin-off of Dalmo-Victor. The name AMPEX is an acronym , created by its founder, which stands for A lexander M . P oniatoff Ex cellence. Ampex operates as Ampex Data Systems Corporation, a subsidiary of Delta Information Systems, and consists of two business units. The Silicon Valley unit, known internally as Ampex Data Systems (ADS), manufactures digital data storage systems capable of functioning in harsh environments. The Colorado Springs, Colorado , unit, referred to as Ampex Intelligent Systems (AIS), serves as

3567-419: Is attempting to do more with the data stored on its network attached storage (NAS) devices. This includes adding encryption for secure data storage; algorithms focused on control system cyber security for infrastructure and aerospace platforms; and artificial intelligence/machine learning for automated entity identification and data analytics. Russian–American inventor Alexander Matthew Poniatoff established

3690-604: Is known as digital composite. Digital Component Technology (DCT) and Data Storage Technology (DST) are VTR and data storage devices respectively, created by Ampex in 1992. Both were similar to the D1 and D2 VTR formats, using a 19-millimetre ( 3 ⁄ 4  in) width, with the DCT format using DCT ( discrete cosine transform ) video compression , also its namesake. The DCT and DST formats yielded relatively high capacity and speed for data and video. Double-density DST data storage

3813-505: Is largely offered in two forms, either chips embedded in smartphones or plastic cards with chips embedded in them. Sony plans to implement this technology in train systems across Asia. In 2019, Sony launched the ELTRES, the company's proprietary low-power wide-area wireless communication ( LPWAN ) standard. Until 1991, Sony had little direct involvement with the video game industry. The company supplied components for other consoles, such as

3936-443: Is organized into the following business segments: Game & Network Services (G&NS), Music, Pictures, Electronics Products & Solutions (EP&S), Imaging & Sensing Solutions (I&SS), Financial Services, and Others. Usually, each business segment has a handful of corresponding intermediate holding companies under which all the related businesses are folded into, such as Columbia Records being part of Sony Music Group ,

4059-573: Is up from their previous ranking as 13th in 2019 with 1,566 applications. Best known for its electronic products, Sony offers a wide variety of product lines in many areas. At its peak, it was dubbed as a "corporate octopus", for its sprawling ventures from private insurance to chemicals to cosmetics to home shopping to a Tokyo-based French food joint, in addition its core businesses such as electronics and entertainment. Even after it has unwound many business units including Sony Chemicals and Vaio PC, Sony still runs diverse businesses. As of 2020, Sony

4182-579: The ATRAC brand, against the more widely used MP3. Until late 2004, Sony's Network Walkman line of digital portable music players did not support the MP3 standard natively. In 2004, Sony built upon the MiniDisc format by releasing Hi-MD . Hi-MD allows the playback and recording of audio on newly introduced 1 GB Hi-MD discs in addition to playback and recording on regular MiniDiscs. In addition to saving audio on

4305-511: The Academy of Motion Picture Arts and Sciences awarded Ampex an Oscar for technical achievement as a result of this development. Les Paul , a friend of Crosby and a regular guest on his shows, had already been experimenting with overdubbed recordings on disc. He received an early portable Ampex Model 300 from Crosby. Using this machine, Les Paul invented "Sound on Sound" recording technology. He placed an additional playback head, located before

4428-824: The Android Open Source Project starting from Android 8.0 " Oreo ", enabling every OEM to integrate this standard into their own Android devices freely. However the decoder library is proprietary , so receiving devices require licenses. On 17 September 2019, the Japan Audio Society (JAS) certified LDAC with their Hi-Res Audio Wireless certification. Currently the only codecs with the Hi-Res Audio Wireless certification are LDAC and LHDC , another competing standard. Sony demonstrated an optical digital audio disc in 1977 and soon joined hands with Philips, another major contender for

4551-635: The Crystal LED Display. Sony used the Compact Cassette format in many of its tape recorders and players, including the Walkman , the world's first portable music player. Sony introduced the MiniDisc format in 1992 as an alternative to Philips DCC or Digital Compact Cassette and as a successor to the Compact Cassette. Since the introduction of MiniDisc, Sony has attempted to promote its own audio compression technologies under

4674-400: The DVD format. However, with many homes still having a large supply of VHS tapes and with all Blu-ray players designed to play regular DVDs and CDs by default , some manufacturers began to make VCR/Blu-ray combo players. Due to the path followed by the video and Hi-Fi audio heads being striped and discontinuous—unlike that of the linear audio track—head-switching is required to provide

4797-574: The Institute of Radio Engineers in San Francisco on May 16, 1946. Bing Crosby , a big star on radio at the time, was receptive to the idea of pre-recording his radio programs. He disliked the regimentation of live broadcasts, and much preferred the relaxed atmosphere of the recording studio. He had already asked the NBC network to let him pre-record his 1944–45 series on transcription discs, but

4920-450: The TR-55 transistor radio , appeared in 1955, but the company name did not change to Sony until January 1958. At the time of the change, it was extremely unusual for a Japanese company to use Roman letters to spell its name instead of writing it in kanji . The move was not without opposition: TTK's principal bank at the time, Mitsui , had strong feelings about the name. They pushed for

5043-535: The Video8 format . Video8 and the follow-on hi-band Hi8 format became popular in the consumer camcorder market. In 1987 Sony launched the 4 mm DAT or Digital Audio Tape as a new digital audio tape standard. Sony held a patent for its proprietary Trinitron until 1996. Sony introduced the Triluminos Display, the company's proprietary color reproduction enhancing technology, in 2004, featured in

5166-415: The 15-inch-per-second (38 cm/s) physical motion. They wrote the video vertically across the width of a tape that was 2 inches (51 mm) wide and ran at 15 inches (38 cm) per second. This allowed hour-long television programs to be recorded on one reel of tape. In 1956, one reel of tape cost $ 300; and Ampex advertised the cost of the recorder as $ 45,000. A 7.5-inch-per-second (19 cm/s) version

5289-485: The 1980s as more and more customers bought VCRs. By 1982, 10% of households in the United Kingdom owned a VCR. The figure reached 30% in 1985 and by the end of the decade well over half of British homes owned a VCR. The two major standards were Sony 's Betamax (also known as Betacord or just Beta), and JVC 's VHS (Video Home System), which competed for sales in what became known as the format war . Betamax

5412-615: The 1990s, and the company turned to digital storage products. Ampex moved into digital storage for DoD Flight Test Instrumentation (FTI) with the introduction of the first, true all digital flight test recorder. Ampex supports numerous major DoD programs with the US Air Force , US Army , US Marines , US Navy and other government entities ( NASA , DHS and national labs). Ampex also works with all major DoD primes and integrators including Boeing , General Atomics , Lockheed , Northrop , Raytheon and many others. Currently, Ampex

5535-518: The Ampex VRX-1000 could be afforded only by the television networks and the largest individual stations. In 1959, Toshiba introduced a new method of recording known as helical scan , releasing the first commercial helical scan video tape recorder that year. It was first implemented in reel-to-reel videotape recorders (VTRs), and later used with cassette tapes. In 1963, Philips introduced its EL3400 1-inch helical scan recorder, aimed at

5658-736: The FM modulator itself. Dolby left Ampex to seek a PhD in physics in England, which is where Dolby Labs was later founded, before moving back to San Francisco. Dolby's brother Dale was also an engineer at Ampex. In 1961, Ampex introduced the first 1-inch helical scan video recorders, the Ampex 2-inch helical VTRs , which recorded video using helical scan recording technology on tape. Ampex 2 inch helical VTRs were manufactured from 1963 to 1970. Model VR-1500 for home. The VR-660 for Broadcast television systems , industrial companies, educational institutions, and

5781-826: The HS-100 video disc recorder. The system was developed by Ampex at the request of the American Broadcasting Company (ABC) for a variety of sports broadcast uses. It was first demonstrated on the air on March 18, 1967, when ABC's Wide World of Sports televised the "World Series of Skiing" from Vail , Colorado . The video was recorded on analog magnetic disc. The disc weighed 5 pounds (2.3 kg) and rotated at 60 rps, 3600 rpm (50 rps in PAL ). One NTSC unit could record 30 seconds of video, PAL units 36 seconds. The video could then be played back in slow motion, stop action to freeze frame. A more deluxe version,

5904-675: The HS-200, was introduced in April 1968, and provided a large control console with variable speed playback. This made it ideal for instant replay for sports events and precise timing control in post-production service. CBS-TV was the first to use the technique during live sportscasts, though it was quickly adopted by all American TV networks. The HS-200, which was an HS-100 connected to a control console, had greater precise frame and timing control capability, lending itself to post-production applications like special effects and titles. The HS-200 had

6027-523: The Memory Stick format with Memory Stick Duo and Memory Stick Micro . The company has also released USB flash drive products, branded under the Micro Vault line. Sony introduced FeliCa , a contactless IC card technology primarily used in contactless payment , as a result of the company's joint development and commercialization of Near-Field Communication (NFC) with Philips. The standard

6150-612: The US include ATSC and QAM support, encouraged major electronics manufacturers to end production of standalone units, with VCR/DVD combo decks being made since then; most of them then can only record from external baseband sources (usually composite video ), including CECBs which (by NTIA mandate) all have composite outputs, as well as those ATSC tuners (including TVs) and cable boxes that come with composite outputs; some combo units that allow recording to DVD do include an ATSC tuner built into them. JVC did ship one model of D-VHS deck with

6273-970: The USA: the headquarters in Hayward, CA (about a dozen miles from the Redwood City location in Silicon Valley), a program office in Colorado Springs, CO and an engineering center in Las Cruces, NM, as well as from the main Delta HQ in Horsham, PA. Ampex continues to produce rugged data storage products used by government, military and commercial customers world-wide. Since joining Delta, Ampex has grown in revenue and headcount, employing significantly more people in 2023 than were employed under

6396-465: The actual VTRs themselves to incorporate SMPTE timecode providing advanced timeline control. The RA-4000 and EDM-1 were fully functional early products, but soon evolved to the extremely powerful ACE family to compete with CMX and other edit controller brands. Starting in the early 1950s, RCA, Bing Crosby and others tried to record analog video on very fast-moving magnetic tape . As early as 1952, Ampex developed prototype video tape recorders that used

6519-424: The analog recording formats for both music and movies that remained in use into the 1990s. Starting in the 1950s, the company began developing video tape recorders , and later introduced the helical scan concept that made home video players possible. They also introduced multi-track recording, slow-motion and instant playback television, and a host of other advances. Ampex's tape business was rendered obsolete during

6642-422: The base and either sticking to the backing of the tape layer wound on top of it (resulting in dropout), or being scraped off and deposited on the tape heads while lifting the head off the tape, degrading the treble. The problem has been reported on a number of makes of tape (usually back-coated tapes), including Ampex tapes. Ampex filed U.S. patent 5,236,790 for a baking process ("A typical temperature used

6765-412: The board. Eventually, Sony President Ohga decided to retain the project after being reminded by Kutaragi of the humiliation he suffered from Nintendo. Nevertheless, due to strong opposition from a majority present at the meeting as well as widespread internal opposition to the project by the older generation of Sony executives, Kutaragi and his team had to be shifted from Sony's headquarters to Sony Music ,

6888-522: The brand as a mix of two words: one was the Latin word " sonus ", which is the root of sonic and sound, and the other was " sonny ", a common slang term used in 1950s America to call a young boy. In 1950s Japan, "sonny boys" was a loan word in Japanese, which connoted smart and presentable young men, which Akio Morita and Masaru Ibuka considered themselves to be. The first Sony-branded product,

7011-411: The broadcast industry for a quarter of a century. The format was licensed to RCA for use in their "television tape recorders." Ampex's invention revolutionized the television production industry by eliminating the kinescope process of time-shifting television programs, which required the use of motion picture film. For archival purposes, the kinescope method continued to be used for some years; film

7134-575: The business and domestic user, and Sony marketed the 2" PV-100, its first reel-to-reel VTR, intended for business, medical, airline, and educational use. The Telcan (Television in a Can), produced by the UK Nottingham Electronic Valve Company in 1963, was the first home video recorder. It was developed by Michael Turner and Norman Rutherford. It could be purchased as a unit or in kit form for £1,337 (equivalent to £35,400 in 2023). There were several drawbacks as it

7257-412: The cassette before the head drum stops spinning. The tape will be extensively damaged, the video heads will often become clogged, and the mechanism may be unable to eject the cassette. The dew sensor itself is mounted very close to the video head drum. Contrary to how one might expect this to behave, the sensor increases its resistance when moisture is present. Poor contacts on the sensor can therefore be

7380-572: The company announced that they would be selling 9.5 million shares in Square Enix (roughly 8.2 percent of the game company's total shares) in a deal worth approximately $ 48 million. In May 2014 the company announced it was forming two joint ventures with Shanghai Oriental Pearl Group to manufacture and market Sony's PlayStation game consoles and associated software in China. In 2015, Sony purchased Toshiba's image sensor business. It

7503-430: The company changed its name to "Sony". Tokyo Tsushin Kogyo founders Morita and Ibuka realized that to achieve success and grow, their business had to expand to the global market, which required labeling their products with a short and easy brand name. While looking for a romanized name, they at first strongly considered using their initials, TTK. The primary reason they did not is that the railway company Tokyo Kyuko

7626-548: The company in San Carlos , California , in 1944 as the Ampex Electric and Manufacturing Company. The company name came from his initials plus "ex" to avoid using the name AMP already in use (by Aircraft and Marine Products). During World War II , Ampex was a subcontractor to Dalmo-Victor, manufacturing high quality electric motors and generators for radars that used alnico 5 magnets from General Electric . Ampex

7749-425: The company's struggling media businesses, encouraging blockbusters such as Spider-Man while cutting 9,000 jobs. He hoped to sell off peripheral business and focus the company again on electronics. Furthermore, he aimed to increase cooperation between business units, which he described as "silos" operating in isolation from one another. In a bid to provide a unified brand for its global operations, Sony introduced

7872-470: The conventional erase/record/playback heads. This allowed Paul to play along with a previously recorded track, both of which were mixed together on to a new track. This was a destructive process because the original recording was recorded over. Ampex built a handful of multitrack machines during the late 1950s that could record as many as eight tracks on 1-inch (25 mm) tape. The project was overseen by Ross Snyder, Ampex manager of special products. To make

7995-461: The development of the Quadruplex video recorder for Ampex was Ray Dolby, who worked under Charlie Ginsburg and went on to form Dolby Laboratories , a pioneer in audio noise reduction systems. Dolby's contribution to the videotape system was limited to the mathematics behind the reactance tube FM modulator, as videotape then used FM modulation for the video portion. Another contributor designed

8118-469: The discs, Hi-MD allows the storage of computer files such as documents, videos and photos. In 1993, Sony challenged the industry standard Dolby Digital 5.1 surround sound format with a newer and more advanced proprietary motion picture digital audio format called SDDS (Sony Dynamic Digital Sound). This format employed eight channels (7.1) of audio opposed to just six used in Dolby Digital 5.1 at

8241-542: The early 1950s, Ampex moved to Redwood City, California. Ampex acquired Orradio Industries in 1959, which became the Ampex Magnetic Tape Division, headquartered in Opelika, Alabama . This made Ampex a manufacturer of both recorders and tape. By the end of that decade Ampex products were much in demand by top recording studios worldwide. In 1952, movie producer Mike Todd asked Ampex to develop

8364-487: The early years owes to a smooth capitalization on the Digital Compact Cassette standard introduced by Philips , with which Sony went on to enjoy a decades-long technological relationship in various areas. Sony (either alone or with partners) has introduced several of the most popular recording formats, including the 3.5-inch floppy disk , compact disc and Blu-ray disc. Sony introduced U-matic ,

8487-817: The film industry and the American public to the Boston strangler : I say to you that the VCR is to the American film producer and the American public as the Boston strangler is to the woman home alone. In the case Sony Corp. of America v. Universal City Studios, Inc. , the Supreme Court of the United States ruled that the device was allowable for private use. Subsequently the film companies found that making and selling video recordings of their productions had become

8610-523: The film studio. According to one report, Sony was set to make a final decision on the possibility of the merger of the TV, film, & gaming businesses by the end of its fiscal year in March of the following year (2017). In 2017, Sony sold its lithium-ion battery business to Murata Manufacturing . In 2019, Sony merged its mobile, TV and camera businesses. On 1 April 2020, Sony Electronics Corporation

8733-429: The first standardized open-reel videotape formats in the 1 inch (25 mm) width; most others of that size at that time were proprietary. 1 inch type C videotape (designated Type C by SMPTE) was a professional open-reel videotape format co-developed and introduced by Ampex and Sony in 1976. It became the replacement in the professional video and television broadcast industries for the then-incumbent Quadruplex. D2

8856-496: The first universally successful optical medium for playback of pre-recorded video, as it gradually overtook VHS to become the most popular consumer format. DVD recorders and other digital video recorders dropped rapidly in price, making the VCR obsolete. DVD rentals in the United States first exceeded those of VHS in June 2003. The declining market, combined with a US FCC mandate effective March 1, 2007, that all new TV tuners in

8979-534: The first-ever U.S. delayed radio broadcast of Bing Crosby's Philco Radio Time . Ampex tape recorders revolutionized the radio and recording industries because of their superior audio quality and ease of operation over audio disk cutting lathes . The firm's earliest production of multichannel machines wasn't aimed at music recording; it noted in 1953–54 that "Ampex began the commercial production of multitrack tape recorders about four years ago for those interested in telemetered information from guided missiles and

9102-612: The fledgling industry from an estimated 100,000 units in 1955 to 5 million units by the end of 1968. Sony co-founder Akio Morita founded Sony Corporation of America in 1960. In the process, he was struck by the mobility of employees between American companies, which was unheard of in Japan at that time. When he returned to Japan, he encouraged experienced, middle-aged employees of other companies to reevaluate their careers and consider joining Sony. The company filled many positions in this manner, and inspired other Japanese companies to do

9225-619: The form of American depositary receipts listed in the New York Stock Exchange (traded since 1961, making it one of the oldest Japanese company to be listed on an American exchange), and was ranked 88th on the 2021 Fortune Global 500 list. In 2023, the company was ranked 57th in the Forbes Global 2000 . Sony began in the wake of World War II. In 1946, Masaru Ibuka started an electronics shop in Shirokiya,

9348-427: The high cost – US$ 1,395 equivalent to $ 10,495 in 2023 for a combination TV/VCR – kept it out of most homes. In 1970, Philips developed a home video cassette format specially made for a TV station in 1970 and available on the consumer market in 1972. Philips named this format " Video Cassette Recording " (although it is also referred to as "N1500", after the first recorder's model number). The industry boomed in

9471-399: The home video game console PlayStation in 1994, which was the first of the eponymous brand . In Japan, Sony expanded into the financial sector. In 2021, Sony transformed into a holding company, handing over the name Sony Corporation to its subsidiary as the electronics company. Sony, with its 55 percent market share in the image sensor market, is the largest manufacturer of image sensors,

9594-503: The introduction of SMPTE time code allowed studios to run multiple machines in perfect synchronization, making the number of available tracks virtually unlimited. By the 1970s, Ampex faced tough competition from the Swiss company Studer and Japanese manufacturers such as Otari and Sony (who also purchased the MCI brand in 1982). In 1979, Ampex introduced their most advanced 24-track recorder,

9717-716: The later VHS cassettes, used 3/4-inch (1.9 cm)-wide tape and had a maximum playing time of 60 minutes, later extended to 80 minutes. Sony also introduced two machines (the VP-1100 videocassette player and the VO-1700, also called the VO-1600 video-cassette recorder) to use the new tapes. U-matic, with its ease of use, quickly made other consumer videotape systems obsolete in Japan and North America, where U-matic VCRs were widely used by television newsrooms (Sony BVU-150 and Trinitron DXC 1810 video camera), schools, and businesses. But

9840-582: The legality of speech in an electronic public forum. After becoming part of Delta Information Systems in 2014, two former subsidiaries of Ampex Corporation continued business as part of the Ampex legacy. Ampex Data Systems Corporation (ADSC) headquartered in Silicon Valley, and its subsidiary, Ampex Japan Ltd. are the only two Ampex businesses that still trade as more than "in name only" entities. Ampex Data Systems operates out of main three locations in

9963-504: The like. These equipments provided any number of simultaneous channels up to 14. It was a simple step, therefore, to make stereophonic tape recorders with two or more channels." During the early 1950s, Ampex began marketing one- and two-track machines using 1 ⁄ 4 -inch (6.4 mm) tape. In May 1953 the firm announced production of two- and three-track machines on 1/4 inch tape. The line soon expanded into three- and four-track models using 1 ⁄ 2 -inch (13 mm) tape. In

10086-466: The many American technological advances. In 1967, Ampex introduced the Ampex VR-3000 portable broadcast video recorder, which revolutionized the recording of broadcast quality television in the field without the need for long cables and large support vehicles. Broadcast quality images could now be shot anywhere, including from airplanes, helicopters and boats. The Quadruplex format dominated

10209-520: The marketbase and became the worldwide standard for consumer VCRs. Betamax is, for all practical purposes, an obsolete format. Sony's professional-oriented component video format called Betacam , which was derived from Betamax, was used until 2016 when Sony announced it was stopping production of all remaining 1/2-inch video tape recorders and players, including the Digital Betacam format. In 1985, Sony launched their Handycam products and

10332-811: The model ATR-124. The ATR-124 was ruggedly constructed and had audio specifications that nearly rivaled the first digital recording machines. However, sales of the ATR-124 were slow due to the machine's high price tag. Ampex sold only about 50 or 60 ATR-124 machines and withdrew from the professional audio tape recorder market entirely in 1983. By the 1990s Ampex focused more on video recorders, instrumentation recorders, and data recorders. In 1991, Ampex sold their professional audio recorder line to Sprague Magnetics. The Ampex Recording Media Corporation spun off in 1995 as Quantegy Inc. ; that company has ceased producing recording tape. While AMPEX are well recognized for their contribution to magnetic tape recording, they also had

10455-570: The multitrack recorder work, Snyder invented the Sel-Sync process, which used some tracks on the head for playback and other tracks on the head for recording. This made the newly recorded material be in sync with the existing recorded tracks. The first of these machines cost $ 10,000 and was installed in Les Paul 's home recording studio by David Sarser . In 1967, Ampex responded to demand by stepping up production of their 8-track machines with

10578-412: The network refused; so Crosby had withdrawn from live radio for a year and returned (this time to the recently created ABC ) for the 1946–47 season, only reluctantly. In June 1947, Mullin, who was pitching the technology to the major Hollywood movie studios, got the chance to demonstrate his modified tape recorders to Crosby. When Crosby heard a demonstration of Mullin's tape recorders, he immediately saw

10701-454: The new Ampex Quadruplex recording system was CBS 's Douglas Edwards and the News on November 30, 1956. The "Quad" head assembly rotates at 14,400 rpm ( NTSC ). The four head pieces (quad) are switched successively so that recorded stripes cross the video portion (most of the tape middle, audio is on one edge, control track is on the other) so that head to tape write speed is well in excess of

10824-567: The new recorders so that Ampex (then a small six-man concern) could develop a commercial production model from the prototypes. Crosby Enterprises was Ampex's West Coast representative until 1957. The company's first tape recorder, the Ampex Model 200A, was first shipped in April 1948. The first two units, serial numbers 1 and 2, were used to record Bing Crosby's show. The American Broadcasting Company used these recorders along with 3M Scotch 111 gamma ferric oxide coated acetate tape for

10947-417: The position of president over to his co-founder Akio Morita. Sony began a life insurance company in 1979, one of its many peripheral businesses. Amid a global recession in the early 1980s, electronics sales dropped and the company was forced to cut prices. Sony's profits fell sharply. "It's over for Sony", one analyst concluded. "The company's best days are behind it." Around that time, Norio Ohga took up

11070-483: The potential of the new technology and commissioned Mullin to prepare a test recording of his radio show. Ampex was finishing its prototype of the Model 200 tape recorder, and Mullin used the first two models as soon as they were built. After a successful test broadcast, ABC agreed to allow Crosby to pre-record his shows on tape. Crosby immediately appointed Mullin as his chief engineer and placed an order for $ 50,000 worth of

11193-723: The previous management structure. The Ampex video system is obsolete, but many thousands of quadruplex videotape recordings remain. Machines that survive are used to transfer archival recordings to modern digital video formats. Sony Sony Group Corporation (formerly Tokyo Tsushin Kogyo K.K. and Sony Corporation ) is a Japanese multinational conglomerate headquartered in Minato, Tokyo , Japan. The Sony Group comprises entities such as Sony Corporation , Sony Semiconductor Solutions , Sony Entertainment (including Sony Pictures and Sony Music Group ), Sony Interactive Entertainment , Sony Financial Group , and others. Sony

11316-548: The production model MM 1000. Like earlier 8-track machines of this era, it used 1-inch tape. In 1966, Ampex built their first 16-track recorder, the model AG-1000, at the request of Mirasound Studios in New York City. In 1967, Ampex introduced a 16-track version of the MM 1000 which was the world's first 16-track professional tape recorder put into mass-production. Both used a 2-inch (51 mm) tape transport design adapted from

11439-414: The quadruplex recording system per se is no longer in use, the principle evolved into the helical scanning technique used in virtually all video tape machines, such as those using the consumer formats of VHS , Sony Betamax and Video 2000 . Sony Betacam was successful as a professional format but operated with a different recording system and faster tape speed than Betamax. One of the key engineers in

11562-552: The role of president. He encouraged the development of the compact disc (CD) in the 1970s and 1980s, and of the PlayStation in the early 1990s. Ohga went on to purchase CBS Records in 1988 and Columbia Pictures in 1989, greatly expanding Sony's media presence. Ohga would succeed Morita as chief executive officer in 1989. Under the vision of co-founder Akio Morita and his successors, the company had aggressively expanded into new businesses. Part of its motivation for doing so

11685-525: The same. Moreover, Sony played a major role in the development of Japan as a powerful exporter during the 1960s, 1970s and 1980s, supplying the U.S. Military with bomb parts used in the Vietnam War . It also helped to significantly improve American perceptions of "made in Japan" products. Known for its production quality, Sony was able to charge above-market prices for its consumer electronics and resisted lowering prices. In 1971, Masaru Ibuka handed

11808-410: The second largest camera manufacturer, and is among the semiconductor sales leaders. It is the world's largest player in the premium TV market for a television of at least 55 inches (140 centimeters) with a price higher than $ 2,500 as well as second largest TV brand by market share and, as of 2020, the third largest television manufacturer in the world by annual sales figures. Although not being

11931-616: The signal, resulting in low-pitched buzzing. Most camcorders produced in the 20th century also feature an integrated VCR. Generally, they include neither a timer nor a TV tuner. Most of these use smaller format videocassettes, such as 8 mm , VHS-C , or MiniDV , although some early models supported full-size VHS and Betamax. In the 21st century, digital recording became the norm while videocassette tapes dwindled away gradually; tapeless camcorders use other storage media such as DVDs, or internal flash memory , hard drive , and SD card . Ampex Ampex Data Systems Corporation

12054-611: The sound chip for the Super Famicom from Nintendo , and operated a video game studio, Sony Imagesoft . As part of a joint project between Nintendo and Sony that began as early as 1988, the two companies worked to create a CD-ROM version of the Super Famicom, though Nintendo denied the existence of the Sony deal as late as March 1991. At the Consumer Electronics Show in June 1991, Sony revealed

12177-598: The specific use of archival data storage, in 1986 and 1988 respectively. In the early 1990s, two high-density optical storage standards were being developed: one was the MultiMedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density Disc (SD), supported by Toshiba and many others. Philips and Sony abandoned their MMCD format and agreed upon Toshiba's SD format with only one modification. The unified disc format

12300-572: The storage technology, to establish a worldwide standard. In 1983, the two company jointly announced the Compact Disc (CD). In 1984, Sony launched the Discman series, an expansion of the Walkman brand to portable CD players. Sony began to improve performance and capacity of the novel format. It launched write-once optical discs (WO) and magneto-optical discs which were around 125MB size for

12423-399: The surface of a tape. The presence of moisture between the tape and the rotating head drum increases friction which prevents correct operation and can cause damage to both the recording device and the tape. In extreme cases, if the dew sensor fails to function and stop the video recorder, moisture can cause the tape to stick to the spinning video head. This can pull a large amount of tape from

12546-505: The technologies developed for the company's optical disc products. In 1983, Sony introduced 90 mm micro diskettes, better known as 3.5-inch (89 mm) floppy disks , which it had developed at a time when there were 4" floppy disks, and many variations from different companies, to replace the then on-going 5.25" floppy disks. Sony had great success and the format became dominant. 3.5" floppy disks gradually became obsolete as they were replaced by current media formats. Sony held more than

12669-515: The time. Ultimately, SDDS has been vastly overshadowed by the preferred DTS ( Digital Theatre System ) and Dolby Digital standards in the motion picture industry. SDDS was solely developed for use in the theatre circuit; Sony never intended to develop a home theatre version of SDDS. Sony and Philips jointly developed the Sony-Philips digital interface format ( S/PDIF ) and the high-fidelity audio system SACD . The latter became entrenched in

12792-491: The two companies. The breaking of the partnership infuriated Sony President Norio Ohga , who responded by appointing Kutaragi with the responsibility of developing the PlayStation project to rival Nintendo. At that time, negotiations were still on-going between Nintendo and Sony, with Nintendo offering Sony a "non-gaming role" regarding their new partnership with Philips. This proposal was swiftly rejected by Kutaragi who

12915-564: The video recording division. The 16-track MM-1000 quickly became legendary for its tremendous flexibility, reliability and outstanding sound quality. This brought about the "golden age" of large format analog multitrack recorders which would last into the mid-1990s. MCI built the first 24-track recorder (using 2-inch tape) in 1968 which was installed at TTG Studios in Los Angeles. Later machines built by Ampex starting in 1969 would have as many as 24 tracks on 2 inch tape. In addition to this,

13038-455: The world's first LED-backlit LCD televisions. It was widely used in other Sony's products as well, including computer monitors, laptops, and smartphones. In 2013, Sony released a new line of televisions with an improved version of the technology, which incorporated quantum dots in the backlight system. It was the first commercial use of quantum dots. In 2012, the company revealed a prototype of an ultrafine RGB LED display, which it calls

13161-518: The world's first videocassette format, in 1971, but the standard was unpopular for domestic use due to the high price. The company subsequently launched the Betamax format in 1975. Sony was involved in the videotape format war of the early 1980s, when they were marketing the Betamax system for video cassette recorders against the VHS format developed by JVC . In the end, VHS gained critical mass in

13284-406: Was available to perform the foreground layering and priority switching – to reduce the burden on the vision mixer with multi-channel effects. AVC – The AVC range of vision mixers ranged from small, single buss devices up to the high-end Century Series, with multiple Mix/Effect busses, infinite re-entry and powerful keying and control software. The product line evolved quickly from manual editing on

13407-525: Was called DVD and was introduced in 1997. Sony was one of the leading developers of the Blu-ray optical disc format, the newest standard for disc-based content delivery. The first Blu-ray players became commercially available in 2006. The format emerged as the standard for HD media over the competing format, Toshiba's HD DVD , after a two-year-long high-definition optical disc format war . Sony's laser communication devices for small satellites rely on

13530-477: Was established as an intermediate holding company to own and oversee its electronics and IT solutions businesses. On 19 May 2020, the company announced that it would change its name to Sony Group Corporation as of 1 April 2021. Subsequently, Sony Electronics Corporation would be renamed to Sony Corporation. On the same day the company announced that it would turn Sony Financial Holdings (currently Sony Financial Group), of which Sony already owns 65.06% of shares, to

13653-442: Was established in 1946 as Tokyo Tsushin Kogyo by Masaru Ibuka and Akio Morita . This electronics company, known for creating products such as the transistor radio TR-55 , the home video tape recorder CV-2000 , the portable audio player Walkman , and the compact disc player CDP-101 , embarked on diverse business ventures. In 1988, Sony acquired CBS Records , and in 1989, it acquired Columbia Pictures . The company also introduced

13776-543: Was expensive, not easy to assemble, and could record only 20 minutes at a time. It recorded in black-and-white, the only format available in the UK at the time as color broadcasts were not available until BBC Two began broadcasting in color in 1967. An original Telcan Domestic Video Recorder can be seen at the Nottingham Industrial Museum . The half-inch tape Sony model CV-2000 , first marketed in 1965,

13899-546: Was facing increasing criticism over his work with regard to entering the video game industry from within Sony. Negotiations officially ended in May 1992 and in order to decide the fate of the PlayStation project, a meeting was held in June 1992, consisting of Sony President Ohga, PlayStation Head Kutaragi and several senior members of Sony's board. At the meeting, Kutaragi unveiled a proprietary CD-ROM-based system he had been working on which involved playing video games with 3D graphics to

14022-478: Was first to market in November 1975, and was argued by many to be technically more sophisticated in recording quality. In the early 1980s US film companies fought to suppress the VCR in the consumer market, citing concerns about copyright violations. In Congressional hearings, Motion Picture Association of America head Jack Valenti decried the "savagery and the ravages of this machine" and likened its effect on

14145-553: Was initially set up in an abandoned loft-space above the Dalmo-Victor plant; eventually they would have offices at 1313 Laurel Street, San Carlos, California (at the intersection of Howard Avenue and Laurel Street). Near the end of the war, while serving in the U.S. Army Signal Corps, Major Jack Mullin was assigned to investigate German radio and electronics experiments. He discovered the Magnetophons with AC biasing on

14268-405: Was introduced in 1996. The final generation of these products were quad density, introduced in 2000, resulting in a large cartridge holding 660GB of data. Some master tapes and other recordings predominantly from the 1970s and 1980s have degraded due to the so-called sticky-shed syndrome . When sticky-shed syndrome occurs, the binding agent deteriorates, resulting in the magnetic coating coming off

14391-882: Was its first VTR intended for home use. It was the first fully transistorized VCR. The development of the videocassette followed the replacement by cassette of other open reel systems in consumer items: the Stereo-Pak four-track audio cartridge in 1962, the compact audio cassette and Instamatic film cartridge in 1963, the 8-track cartridge in 1965, and the Super 8 home movie cartridge in 1966. In 1972, videocassettes of movies became available for home use through Cartrivision . The format never became widely popular because recorders were expensive (retailing for $ 1,350 (equivalent to $ 9,266 in 2023)) and players were not available as standalone units. Cassettes intended for home use were encased in black plastic, and could be rewound by

14514-411: Was known as TTK. The company occasionally used the syllabic acronym "Totsuko" in Japan, but during his visit to the United States, Morita discovered that Americans had trouble pronouncing that name. Another early name that was tried out for a while was "Tokyo Teletech" until Akio Morita discovered that there was an American company already using Teletech as a brand name. The name "Sony" was chosen for

14637-422: Was picked up by Atlantic Records . In 2005, iNEXTV, a wholly owned subsidiary of respondent Ampex Corporation, brought a defamation lawsuit against a poster on an Internet message board who posted messages critical of them (Ampex Corp. v. Cargle (2005), Cal.App.4th). The poster, a former employee, responded with an anti- SLAPP suit and eventually recovered his attorney fees. The case was unique in that it involved

14760-409: Was released later, and this required a new, narrower headwheel. This vertical writing facilitated mechanical editing, once the control track was developed to display the pulse that indicates where a frame ends and the next one begins. Later, Ampex developed electronic editing. The National Academy of Television Arts and Sciences awarded Ampex its first Emmy in 1957 for this development. Ampex received

14883-483: Was reported in December 2016 by multiple news outlets that Sony was considering restructuring its U.S. operations by merging its TV & film business, Sony Pictures Entertainment, with its gaming business, Sony Interactive Entertainment. According to the reports, such a restructuring would have placed Sony Pictures under Sony Interactive's CEO, Andrew House, though House would not have taken over day-to-day operations of

15006-399: Was still preferred by archivists. The Ampex broadcast video tape recorder facilitated time-zone broadcast delay so that networks could air programming at the same hour in various time zones. Ampex had trademarked the name " video tape ", so competitor RCA called the medium "TV tape" or "television tape". The terms eventually became genericized , and "videotape" is commonly used today. While

15129-492: Was the pursuit of "convergence", linking film, music and digital electronics via the Internet. This expansion proved unrewarding and unprofitable, threatening Sony's ability to charge a premium on its products as well as its brand name. In 2005, Howard Stringer replaced Nobuyuki Idei as chief executive officer, marking the first time that a foreigner had run a major Japanese electronics firm. Stringer helped to reinvigorate
