ATAPI ( ATA Packet Interface ) is a protocol used with the Parallel ATA (IDE) and Serial ATA standards so that a greater variety of devices can be connected to a computer than with the ATA command set alone. It carries SCSI commands and responses through the ATA interface.
90-615: ATAPI devices include CD-ROM and DVD-ROM drives, tape drives , magneto-optical drives , and large-capacity floppy drives such as the Zip drive and SuperDisk drive . ATA was originally designed for, and worked only with, hard disks and devices that could emulate them. A group called the Small Form Factor committee (SFF) introduced ATAPI to be used for a variety of other devices that require functions beyond those necessary for hard disks. For example, any removable media device needs

DVDs are used in DVD-Video consumer digital video format and less commonly in DVD-Audio consumer digital audio format, as well as for authoring DVD discs written in a special AVCHD format to hold high definition material (often in conjunction with AVCHD format camcorders ). DVDs containing other types of information may be referred to as DVD data discs. The Oxford English Dictionary comments that, "In 1995, rival manufacturers of
270-646: A "media eject" command, and a way for the host to determine whether the media is present, and these were not provided in the ATA protocol. The Small Form Factor committee approached this problem by defining ATAPI as part of the fourth generation of ATA. ATAPI carries SCSI commands through ATA, so ATAPI devices are "speaking SCSI" other than at the electrical interface. In fact, some early ATAPI devices were simply SCSI devices with an ATA/ATAPI to SCSI protocol converter added on. The SCSI commands and responses are embedded in "packets" (hence "ATA Packet Interface") for transmission on

Read and write speeds for the first DVD drives and players were 1,385 kB /s (1,353 KiB /s); this speed is usually called "1×". More recent models, at 18× or 20×, have 18 or 20 times that speed. For CD drives, 1× means 153.6 kB/s (150 KiB/s), about one-ninth as swift. DVDs can spin at much higher speeds than CDs – DVDs can spin at up to 32000 RPM vs 23000 for CDs. In practice, they are not spun by optical drives anywhere close to these speeds to provide

The nationwide rollout for the format happened on August 22, 1997. DTS announced in late 1997 that they would be coming onto the format. The sound system company revealed details in
6030-451: The original film recordings. Shows that were made between the early 1980s and the early 2000s were generally shot on film, then transferred to video tape, and then edited natively in either NTSC or PAL; this makes high-definition transfers impossible, as these SD standards were baked into the final cuts of the episodes. Star Trek: The Next Generation was the only such show that had a Blu-ray release, as prints were re-scanned and edited from
6120-547: The present Anritsu . After the demise of the founder in 1881, Tanaka Seisakusho became partly owned by General Electric and expanded into the production of torpedoes and mines at the request of the Imperial Japanese Navy , to become one of the largest manufacturing companies of the time. However, as the Navy started to use competitive bids and then build its own works, the demand decreased substantially and
6210-540: The product initially named digital video disc agreed that, in order to emphasize the flexibility of the format for multimedia applications, the preferred abbreviation DVD would be understood to denote digital versatile disc." The OED also states that in 1995, "The companies said the official name of the format will simply be DVD. Toshiba had been using the name 'digital video disc', but that was switched to 'digital versatile disc' after computer companies complained that it left out their applications." "Digital versatile disc"
6300-412: The sales of DVDs and Blu-rays for the first time. Until the end of the 2010s, manufacturers continued to release standard DVD titles as of 2020 , and the format remained the preferred one for the release of older television programs and films. Shows that were shot and edited entirely on film, such as Star Trek: The Original Series , could not be released in high definition without being re-scanned from
6390-433: The same dimensions. A standard single-layer DVD can store up to 4.7 GB of data, a dual-layer DVD up to 8.5 GB. Variants can store up to a maximum of 17.08 GB. Prerecorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are a form of DVD-ROM because data can only be read and not written or erased. Blank recordable DVD discs ( DVD-R and DVD+R ) can be recorded once using
6480-414: The same side—instead of proposal SD 10, which would have created a two-sided disc that users would have to turn over. Philips/Sony strongly insisted on the source code, EFMPlus , that Kees Schouhamer Immink had designed for the MMCD, because it makes it possible to apply the existing CD servo technology. Its drawback was a loss from 5 to 4.7 Gbyte of capacity. As a result, the DVD specification provided
6570-544: The shares of the Swiss-based advanced-power-meter maker Landis+Gyr for $ 2.3 billion.

6660-663: The slightly lower data density of dual layer DVDs (4.25 GB instead of 4.7 GB per layer), the required rotation speed is around 10% faster for the same data rate, which means that the same angular speed rating equals a 10% higher physical angular rotation speed. For that reason, the increase of reading speeds of dual layer media has stagnated at 12× ( constant angular velocity ) for half-height optical drives released since around 2005, and slim type optical drives are only able to record dual layer media at 6× (constant angular velocity), while reading speeds of 8× are still supported by such. The quality and data integrity of optical media
6750-619: The sponsor of the top-most screen of One Times Square in New York City .

The merger of Shibaura and Tokyo Denki created a new company called Tokyo Shibaura Denki (Tokyo Shibaura Electric) ( 東 京 芝 浦 電気 ). It was soon nicknamed Toshiba, but it
6930-416: The total nominal capacity of a DVD-10 disc to 9.4 GB (8.75 GiB), but each side is locked to 4.7 GB. Like DVD-5 discs, DVD-10 discs are defined as single-layer (SL) discs. DVD hardware accesses the additional layer (layer 1) by refocusing the laser through an otherwise normally-placed, semitransparent first layer (layer 0). This laser refocus—and the subsequent time needed to reacquire laser tracking—can cause
7020-477: The two previous CEOs. Chairman Masashi Muromachi was appointed acting CEO. Following the scandal, Toshiba Corp. was removed from a stock index showcasing Japan's best companies. That was the second reshuffle of the index, which picks companies with the best operating income, return on equity and market value. Toshiba announced in early 2015 that they would stop making televisions in its own factories. From 2015 onward, Toshiba televisions will be made by Compal for
7110-430: The ubiquitous VHS tape as the primary consumer video distribution format. Immediately following the formal adoption of a unified standard for DVD, two of the four leading video game console companies ( Sega and The 3DO Company ) said they already had plans to design a gaming console with DVDs as the source medium. Sony stated at the time that they had no plans to use DVD in their gaming systems, despite being one of

7380-413: Was an increased demand of high definition media, where Ultra HD Blu-ray and regular Blu-ray formats made up for almost half of the US market while sales of physical media continued to shrink in favor of streaming services. Longevity of a storage medium is measured by how long the data remains readable, assuming compatible devices exist that can read it: that is, how long the disc can be stored until data
7470-459: Was completed on 21 January 2014 when the assets of OCZ Technology Group became a new independently operated subsidiary of Toshiba named OCZ Storage Solutions. OCZ Technology Group then changed its name to ZCO Liquidating Corporation; on 18 August 2014, ZCO Liquidating Corporation and its subsidiaries were liquidated.
