102-494: The company has developed as one of manufacturing and research and development (formerly known as Seikosha ) of the former Seiko Group , a name traditionally known for manufacturing Seiko timepieces . Seiko Epson was one of the major companies in the Seiko Group, but is neither a subsidiary nor an affiliate of Seiko Group Corporation. The roots of Seiko Epson Corporation go back to a company called Daiwa Kogyo, Ltd. which

204-684: A spindle that holds flat circular disks, called platters , which hold the recorded data. The platters are made from a non-magnetic material, usually aluminum alloy , glass , or ceramic . They are coated with a shallow layer of magnetic material typically 10–20 nm in depth, with an outer layer of carbon for protection. For reference, a standard piece of copy paper is 0.07–0.18 mm (70,000–180,000 nm) thick. The platters in contemporary HDDs are spun at speeds varying from 4200  rpm in energy-efficient portable devices, to 15,000 rpm for high-performance servers. The first HDDs spun at 1,200 rpm and, for many years, 3,600 rpm

306-603: A printer control language , the Epson Standard Code for Printers (or ESC/P ). It became a de facto industry standard for controlling print formatting during the era of dot matrix printers , whose popularity was initially started by the Epson MX-80. Epson Robots is the robotics design and manufacturing department of Epson. Seiko Epson produces some microcontrollers, such as the S1C63 . In 1980, Epson started

408-522: A stepper motor . Early hard disk drives wrote data at some constant bits per second, resulting in all tracks having the same amount of data per track, but modern drives (since the 1990s) use zone bit recording , increasing the write speed from inner to outer zone and thereby storing more data per track in the outer zones. In modern drives, the small size of the magnetic regions creates the danger that their magnetic state might be lost because of thermal effects ⁠ ⁠— thermally induced magnetic instability which

510-416: A "stopgap" technology between PMR and Seagate's intended successor heat-assisted magnetic recording (HAMR). SMR utilises overlapping tracks for increased data density, at the cost of design complexity and lower data access speeds (particularly write speeds and random access 4k speeds). By contrast, HGST (now part of Western Digital ) focused on developing ways to seal helium -filled drives instead of

612-582: A Field Generation Layer (FGL) and a Spin Injection Layer (SIL), and the FGL produces a magnetic field using spin-polarised electrons originating in the SIL, which is a form of spin torque energy. A typical HDD has two electric motors: a spindle motor that spins the disks and an actuator (motor) that positions the read/write head assembly across the spinning disks. The disk motor has an external rotor attached to

714-418: A bit cell comprising about 18 magnetic grains (11 by 1.6 grains). Since the mid-2000s, areal density progress has been challenged by a superparamagnetic trilemma involving grain size, grain magnetic strength and ability of the head to write. In order to maintain acceptable signal-to-noise, smaller grains are required; smaller grains may self-reverse ( electrothermal instability ) unless their magnetic strength

816-489: A breather port, unlike their air-filled counterparts. Other recording technologies are either under research or have been commercially implemented to increase areal density, including Seagate's heat-assisted magnetic recording (HAMR). HAMR requires a different architecture with redesigned media and read/write heads, new lasers, and new near-field optical transducers. HAMR is expected to ship commercially in late 2024, after technical issues delayed its introduction by more than

918-453: A cartridge doesn't have enough ink to complete the cleaning, a fuller cartridge must be used. However, users have the choice to swap out a cartridge that is reporting low levels for a fuller cartridge for the cleaning maintenance as needed, and then replace it with the original cartridge to use the remaining ink. The original cartridge does not need to be discarded. Research and development Research and development ( R&D or R+D )

1020-526: A complaint with the U.S. International Trade Commission (ITC) in February 2006 against 24 companies that manufactured, imported, or distributed Epson- compatible ink cartridges for resale in the U.S. On March 30, 2007, ITC judge Paul Luckern issued an initial determination that the cartridges in question did infringe upon Epson's patents . He also recommended those companies and others to be barred from manufacturing, importing, or reselling Epson cartridges in

1122-449: A component of the IBM 305 RAMAC system. It was approximately the size of two large refrigerators and stored five million six-bit characters (3.75 megabytes ) on a stack of 52 disks (100 surfaces used). The 350 had a single arm with two read/write heads, one facing up and the other down, that moved both horizontally between a pair of adjacent platters and vertically from one pair of platters to

1224-1087: A decade, from earlier projections as early as 2009. HAMR's planned successor, bit-patterned recording (BPR), has been removed from the roadmaps of Western Digital and Seagate. Western Digital's microwave-assisted magnetic recording (MAMR), also referred to as energy-assisted magnetic recording (EAMR), was sampled in 2020, with the first EAMR drive, the Ultrastar HC550, shipping in late 2020. Two-dimensional magnetic recording (TDMR) and "current perpendicular to plane" giant magnetoresistance (CPP/GMR) heads have appeared in research papers. Some drives have adopted dual independent actuator arms to increase read/write speeds and compete with SSDs. A 3D-actuated vacuum drive (3DHD) concept and 3D magnetic recording have been proposed. Depending upon assumptions on feasibility and timing of these technologies, Seagate forecasts that areal density will grow 20% per year during 2020–2034. The highest-capacity HDDs shipping commercially in 2024 are 32 TB. The capacity of

1326-599: A factory in Suwa for manufacturing Seiko watches with Daiwa Kogyo. In 1959, the Suwa Factory was split up and merged into Daiwa Kogyo to form Suwa Seikosha Co., Ltd: the forerunner of the Seiko Epson Corporation. The company has developed many timepiece technologies, such as the world's first portable quartz timer (Seiko QC-951) in 1963, the world's first quartz watch ( Seiko Quartz Astron 35SQ ) in 1969,

1428-527: A printing timer was required to time events, and Shinshu Seiki started developing an electronic printer. In September 1968, Shinshu Seiki launched the world's first mini-printer, the EP-101 ("EP" for Electronic Printer), which was soon incorporated into many calculators. In June 1975, the name Epson was coined for the next generation of printers based on the EP-101, which was released to the public. The Epson name

1530-475: A removable disk module, which included both the disk pack and the head assembly, leaving the actuator motor in the drive upon removal. Later "Winchester" drives abandoned the removable media concept and returned to non-removable platters. In 1974, IBM introduced the swinging arm actuator, made feasible because the Winchester recording heads function well when skewed to the recorded tracks. The simple design of

1632-538: A second set. Variants of the IBM 350 were the IBM 355 , IBM 7300 and IBM 1405 . In 1961, IBM announced, and in 1962 shipped, the IBM ;1301 disk storage unit, which superseded the IBM 350 and similar drives. The 1301 consisted of one (for Model 1) or two (for model 2) modules, each containing 25 platters, each platter about 1 ⁄ 8 -inch (3.2 mm) thick and 24 inches (610 mm) in diameter. While

1734-454: A subsidiary of Seiko Group. The watch brand Orient Watch , also known as Orient Star, has been owned by Epson since 2009 and was fully integrated into the company in 2017. In 1961, Suwa Seikosha established a company called Shinshu Seiki Co. as a subsidiary to supply precision parts for Seiko watches. When Seiko was selected to be the official time keeper for the 1964 Summer Olympics in Tokyo,

1836-616: A swing arm drive, the IBM 0680 (Piccolo), with eight inch platters, exploring the possibility that smaller platters might offer advantages. Other eight inch drives followed, then 5 + 1 ⁄ 4  in (130 mm) drives, sized to replace the contemporary floppy disk drives . The latter were primarily intended for the then fledgling personal computer (PC) market. Over time, as recording densities were greatly increased, further reductions in disk diameter to 3.5" and 2.5" were found to be optimum. Powerful rare earth magnet materials became affordable during this period, and were complementary to

1938-423: A thin film of ferromagnetic material on both sides of a disk. Sequential changes in the direction of magnetization represent binary data bits . The data is read from the disk by detecting the transitions in magnetization. User data is encoded using an encoding scheme, such as run-length limited encoding, which determines how the data is represented by the magnetic transitions. A typical HDD design consists of

2040-499: A tiny fraction of the detected errors end up as not correctable. Examples of specified uncorrected bit read error rates include: Within a given manufacturers model the uncorrected bit error rate is typically the same regardless of capacity of the drive. The worst type of errors are silent data corruptions which are errors undetected by the disk firmware or the host operating system; some of these errors may be caused by hard disk drive malfunctions while others originate elsewhere in

2142-730: A type of non-volatile storage , retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box . Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers , though personal computing devices produced in large volume, like mobile phones and tablets , rely on flash memory storage devices. More than 224 companies have produced HDDs historically , though after extensive industry consolidation, most units are manufactured by Seagate , Toshiba , and Western Digital . HDDs dominate

2244-445: A way of amortizing the high overhead. They often reuse advanced manufacturing processes, expensive safety certifications, specialized embedded software, computer-aided design software, electronic designs and mechanical subsystems. Research from 2000 has shown that firms with a persistent R&D strategy outperform those with an irregular or no R&D investment program. Research and development are very difficult to manage, since

2346-476: Is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads , usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are

2448-660: Is appealing to bidders because they could gain technologies from acquisition targets. Therefore, firms may gain R&;D profit that co-moves with takeover waves, causing risks to the company which engages in R&D activity. Global R&D management is the discipline of designing and leading R&D processes globally, across cultural and lingual settings, and the transfer of knowledge across international corporate networks. Former President Barack Obama requested $ 147.696 billion for research and development in FY 2012, 21% of which

2550-446: Is capable of scheduling reads and writes efficiently on the platter surfaces and remapping sectors of the media that have failed. Modern drives make extensive use of error correction codes (ECCs), particularly Reed–Solomon error correction . These techniques store extra bits, determined by mathematical formulas, for each block of data; the extra bits allow many errors to be corrected invisibly. The extra bits themselves take up space on

2652-590: Is commonly known as the " superparamagnetic limit ". To counter this, the platters are coated with two parallel magnetic layers, separated by a three-atom layer of the non-magnetic element ruthenium , and the two layers are magnetized in opposite orientation, thus reinforcing each other. Another technology used to overcome thermal effects to allow greater recording densities is perpendicular recording (PMR), first shipped in 2005, and as of 2007 , used in certain HDDs. Perpendicular recording may be accompanied by changes in

2754-483: Is followed by textiles (19%), digital (18%), and aerospace (15%). Other sectors allocate less than 10% of their total investment to R&D. While 17% of the world’s top R&D investors are based in the European Union, they accounted for only 1% of acquisitions involving EU-based companies between 2013 and 2023. In 2015, research and development constituted an average 2.2% of the global GDP according to

2856-669: Is improving faster than HDDs. NAND has a higher price elasticity of demand than HDDs, and this drives market growth. During the late 2000s and 2010s, the product life cycle of HDDs entered a mature phase, and slowing sales may indicate the onset of the declining phase. The 2011 Thailand floods damaged the manufacturing plants and impacted hard disk drive cost adversely between 2011 and 2013. In 2019, Western Digital closed its last Malaysian HDD factory due to decreasing demand, to focus on SSD production. All three remaining HDD manufacturers have had decreasing demand for their HDDs since 2014. A modern HDD records data by magnetizing

2958-418: Is increased, but known write head materials are unable to generate a strong enough magnetic field sufficient to write the medium in the increasingly smaller space taken by grains. Magnetic storage technologies are being developed to address this trilemma, and compete with flash memory –based solid-state drives (SSDs). In 2013, Seagate introduced shingled magnetic recording (SMR), intended as something of

3060-641: Is lower than the EU average of 18%. In 2022, 67% of enterprises in the same region deployed at least one sophisticated digital technology, and 69% EU firms did the same. As of 2023, European enterprises account for 18% of the world's top 2 500 R&D corporations, but just 10% of new entrants, compared to 45% in the United States and 32% in China. As of 2024, the electronics sector leads in R&D investment, with 28% of its total investment dedicated to it. This

3162-404: Is necessary as well due to the fierce competition and the evolving preferences of consumers. Without an R&D program, a firm must rely on strategic alliances , acquisitions , and networks to tap into the innovations of others. A system driven by marketing is one that puts the customer needs first, and produces goods that are known to sell. Market research is carried out, which establishes

3264-479: Is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment . R&D is crucial for acquiring larger shares of the market through new products. R&D&I represents R&D with innovation. New product design and development is often a crucial factor in the survival of a company. In a global industrial landscape that is changing fast, firms must continually revise their design and range of products. This

3366-596: Is remarkable, and usually gains a reputation for being a high technology company such as engineering company Ericsson 24.9%, or biotech company Allergan , which tops the spending table with 43.4% investment. Such companies are often seen as credit risks because their spending ratios are so unusual. Generally such firms prosper only in markets whose customers have extreme high technology needs, like certain prescription drugs or special chemicals, scientific instruments , and safety-critical systems in medicine, aeronautics or military weapons . The extreme needs justify

3468-460: Is shaped rather like an arrowhead and is made of doubly coated copper magnet wire . The inner layer is insulation, and the outer is thermoplastic, which bonds the coil together after it is wound on a form, making it self-supporting. The portions of the coil along the two sides of the arrowhead (which point to the center of the actuator bearing) then interact with the magnetic field of the fixed magnet. Current flowing radially outward along one side of

3570-588: Is specified in unit prefixes corresponding to powers of 1000: a 1- terabyte (TB) drive has a capacity of 1,000 gigabytes , where 1 gigabyte = 1 000 megabytes = 1 000 000 kilobytes (1 million) = 1 000 000 000 bytes (1 billion). Typically, some of an HDD's capacity is unavailable to the user because it is used by the file system and the computer operating system , and possibly inbuilt redundancy for error correction and recovery. There can be confusion regarding storage capacity, since capacities are stated in decimal gigabytes (powers of 1000) by HDD manufacturers, whereas

3672-446: Is the set of innovative activities undertaken by corporations or governments in developing new services or products. R&D constitutes the first stage of development of a potential new service or the production process. Although R&D activities may differ across businesses, the primary goal of an R&D department is to develop new products and services. R&D differs from the vast majority of corporate activities in that it

3774-645: The Apple Macintosh . Many Macintosh computers made between 1986 and 1998 featured a SCSI port on the back, making external expansion simple. Older compact Macintosh computers did not have user-accessible hard drive bays (indeed, the Macintosh 128K , Macintosh 512K , and Macintosh Plus did not feature a hard drive bay at all), so on those models, external SCSI disks were the only reasonable option for expanding upon any internal storage. HDD improvements have been driven by increasing areal density , listed in

3876-451: The Europe 2020 strategy which will run from 2014 to 2020, a multidisciplinary effort to provide safe, economically feasible, environmentally sound and socially acceptable solutions along the entire value chain of human activities. Firms that have embraced advanced digital technology devote a greater proportion of their investment efforts to R&D. Firms who engaged in digitisation during

3978-759: The MX-80 (MP-80), was launched in October 1980. It was soon advertised as the best selling printer in the United States . In July 1982, Shinshu Seiki officially named itself the Epson Corporation and launched the world's first handheld computer, the HX-20 (HC-20), and in May 1983, the world's first portable colour LCD TV was developed and launched by the company. In November 1985, Suwa Seikosha Co., Ltd. and

4080-628: The Office of Chief Scientist In the 1980s to 1992, the Chief scientist of Israel significantly expanded R&D subsidies in the Israeli industrial sector. Israel invested in the creation of clusters of startups in the high-tech sector as well as venture capital investments. In 1993, Israel initiated the Yozma program , which led to the doubling of value of Israel's 10 new venture capital funds in 3 years. In

4182-663: The QX-10 , a CP/M -compatible Z80 machine. By 1986, the company had shifted to the growing PC market with the Equity line. EPSON manufactured and sold NEC PC-9801 clones in Japan. Epson withdrew from the international PC market in 1996. The company still produces and sells PCs in Japan as of 2024. In June 2003, the company became public following their listing on the 1st section of the Tokyo Stock Exchange . Since 2017,

4284-572: The Shannon limit and thus provide the highest storage density available. Typical hard disk drives attempt to "remap" the data in a physical sector that is failing to a spare physical sector provided by the drive's "spare sector pool" (also called "reserve pool"), while relying on the ECC to recover stored data while the number of errors in a bad sector is still low enough. The S.M.A.R.T ( Self-Monitoring, Analysis and Reporting Technology ) feature counts

4386-626: The UNESCO Institute for Statistics . By 2018, research and development constituted an average 1.79% of the global GDP according to the UNESCO Institute for Statistics . Countries agreed in 2015 to monitor their progress in raising research intensity (SDG 9.5.1), as well as researcher density (SDG 9.5.2), as part of their commitment to reaching the Sustainable Development Goals by 2030. However, this undertaking has not spurred an increase in reporting of data. On

4488-658: The Epson Corporation merged to form Seiko Epson Corporation. The company developed the Micro Piezo inkjet technology, which used a piezoelectric crystal in each nozzle and did not heat the ink at the print head while spraying it onto the page, and released the Epson MJ-500 inkjet cartridge for the Epson Stylus 800 printer in March 1993. Shortly after in 1994, Epson released the first 720 dpi colour inkjet printer,

4590-606: The Epson Stylus Color (P860A) utilizing the Micro Piezo head technology. Newer models of the Stylus series employed Epson's special DURABrite ink and used two hard drives (an HD 850 and an HD 860). In 1994, Epson started to outsource sales representatives to help sell their products in retail stores in the United States. The same year, they started the Epson Weekend Warrior sales program. The purpose of

4692-526: The HDD, but allow higher recording densities to be employed without causing uncorrectable errors, resulting in much larger storage capacity. For example, a typical 1  TB hard disk with 512-byte sectors provides additional capacity of about 93  GB for the ECC data. In the newest drives, as of 2009 , low-density parity-check codes (LDPC) were supplanting Reed–Solomon; LDPC codes enable performance close to

4794-481: The IBM GV (Gulliver) drive, invented at IBM's UK Hursley Labs, became IBM's most licensed electro-mechanical invention of all time, the actuator and filtration system being adopted in the 1980s eventually for all HDDs, and still universal nearly 40 years and 10 billion arms later. Like the first removable pack drive, the first "Winchester" drives used platters 14 inches (360 mm) in diameter. In 1978, IBM introduced

4896-461: The Mosaic contract expired. The sales reps of Campaigners, Inc. are not outsourced; Epson hired rack jobbers to ensure retailers displayed products properly, freeing up its regular sales force to concentrate on profitable sales solutions to value-added resellers and system integrators, leaving "retail" to reps who did not require sales skills. Epson entered the personal computer market in 1983 with

4998-565: The R-D1 up to the full functionality of its successor, being the first digital camera manufacturer to make such an upgrade available for free. In September 2012, Epson introduced a printer called the Expression Premium XP-800 Small-in-One, with the ability to print wirelessly. The Expression brand name has since been used on various models of scanners. In the third quarter of 2012, Epson's global market share in

5100-452: The U.S., said Epson. In 2015, it emerged that Epson printers reported cartridges to be empty when in fact up to 20% of their ink remains. As in 2003, the company responded: The ink reporting and ink cartridges used in Epson's Stylus Pro 9900-series large format printer reports on ink levels and simultaneously protect the health of the printhead . During printhead maintenance or cleanings, if

5202-443: The arrowhead and radially inward on the other produces the tangential force . If the magnetic field were uniform, each side would generate opposing forces that would cancel each other out. Therefore, the surface of the magnet is half north pole and half south pole, with the radial dividing line in the middle, causing the two sides of the coil to see opposite magnetic fields and produce forces that add instead of canceling. Currents along

5304-433: The best measures, because they are continuously maintained, public and reflect risk. In the United States, a typical ratio of research and development for an industrial company is about 3.5% of revenues; this measure is called " R&D intensity ". A high technology company, such as a computer manufacturer, might spend 7% or a pharmaceutical companies such as Merck & Co. 14.1% or Novartis 15.1%. Anything over 15%

5406-450: The case of embedded servo, otherwise known as sector servo technology). The servo feedback optimizes the signal-to-noise ratio of the GMR sensors by adjusting the voice coil motor to rotate the arm. A more modern servo system also employs milli and/or micro actuators to more accurately position the read/write heads. The spinning of the disks uses fluid-bearing spindle motors. Modern disk firmware

5508-607: The company is a constituent of the Nikkei Stock Average index. Although Seiko Group Corporation ( f/k/a K. Hattori, Hattori Seiko, and Seiko Holdings) and the key members of the Hattori family still hold approximately 10% of the outstanding shares of Seiko Epson, the company is managed and operated completely independently from Seiko Group. Seiko Watch Corporation, a division of Seiko Group, produces Seiko timepieces in-house through its subsidiaries as well as delegates

5610-441: The connection between the drive and the host. The rate of areal density advancement was similar to Moore's law (doubling every two years) through 2010: 60% per year during 1988–1996, 100% during 1996–2003 and 30% during 2003–2010. Speaking in 1997, Gordon Moore called the increase "flabbergasting", while observing later that growth cannot continue forever. Price improvement decelerated to −12% per year during 2010–2017, as

5712-553: The context of commerce , "research and development" normally refers to future-oriented, longer-term activities in science or technology , using similar techniques to scientific research but directed toward desired outcomes and with broad forecasts of commercial yield. Statistics on organizations devoted to "R&D" may express the state of an industry , the degree of competition or the lure of progress . Some common measures include: budgets , numbers of patents or on rates of peer-reviewed publications . Bank ratios are one of

5814-534: The contrary, a total of 99 countries reported data on domestic investment in research in 2015 but only 69 countries in 2018. Similarly, 59 countries recorded the number of researchers (in full-time equivalents) in 2018, down from 90 countries in 2015. UNESCO Institute for Statistics is the global custodian of these R&D data; data can be freely obtained from the UIS database . Hard disk drive A hard disk drive ( HDD ), hard disk , hard drive , or fixed disk

5916-411: The defining feature of research is that the researchers do not know in advance exactly how to accomplish the desired result. As a result, "higher R&D spending does not guarantee more creativity, higher profit or a greater market share". Research is the most risky financing area because both the development of an invention and its successful realization carries uncertainty including the profitability of

6018-449: The disks; the stator windings are fixed in place. Opposite the actuator at the end of the head support arm is the read-write head; thin printed-circuit cables connect the read-write heads to amplifier electronics mounted at the pivot of the actuator. The head support arm is very light, but also stiff; in modern drives, acceleration at the head reaches 550 g . The actuator is a permanent magnet and moving coil motor that swings

6120-467: The earlier IBM disk drives used only two read/write heads per arm, the 1301 used an array of 48 heads (comb), each array moving horizontally as a single unit, one head per surface used. Cylinder-mode read/write operations were supported, and the heads flew about 250 micro-inches (about 6 μm) above the platter surface. Motion of the head array depended upon a binary adder system of hydraulic actuators which assured repeatable positioning. The 1301 cabinet

6222-557: The first automatic power-generating quartz watch (Seiko Auto-Quartz) in 1988, and the Spring Drive watch movement in 1999. The watch business is the root of the company's ultra-precision machining and micromechatronics technologies and still a major business for Seiko Epson, although it accounts for a low percentage of total revenues. Watches made by the company are sold through the Seiko Watch Corporation,

6324-443: The growth of areal density slowed. The rate of advancement for areal density slowed to 10% per year during 2010–2016, and there was difficulty in migrating from perpendicular recording to newer technologies. As bit cell size decreases, more data can be put onto a single drive platter. In 2013, a production desktop 3 TB HDD (with four platters) would have had an areal density of about 500 Gbit/in which would have amounted to

6426-416: The heads to the desired position. A metal plate supports a squat neodymium–iron–boron (NIB) high-flux magnet . Beneath this plate is the moving coil, often referred to as the voice coil by analogy to the coil in loudspeakers , which is attached to the actuator hub, and beneath that is a second NIB magnet, mounted on the bottom plate of the motor (some drives have only one magnet). The voice coil itself

6528-445: The high risk of failure and consequently high gross margins from 60% to 90% of revenues. That is, gross profits will be as much as 90% of the sales cost, with manufacturing costing only 10% of the product price, because so many individual projects yield no exploitable product. Most industrial companies get 40% revenues only. On a technical level, high tech organizations explore ways to re-purpose and repackage advanced technologies as

6630-782: The invention. One way entrepreneurs can reduce these uncertainties is to buy the licence for a franchise, so that the know-how is already incorporated in the licence. In general, it has been found that there is a positive correlation between the research and development and firm productivity across all sectors, but that this positive correlation is much stronger in high-tech firms than in low-tech firms. In research done by Francesco Crespi and Cristiano Antonelli, high-tech firms were found to have "virtuous" Matthew effects while low-tech firms experienced "vicious" Matthew effects, meaning that high-tech firms were awarded subsidies on merit while low-tech firms most often were given subsidies based on name recognition, even if not put to good use. While

6732-427: The largest hard drive had a capacity of 15 TB, while the largest capacity SSD had a capacity of 100 TB. As of 2018 , HDDs were forecast to reach 100 TB capacities around 2025, but as of 2019 , the expected pace of improvement was pared back to 50 TB by 2026. Smaller form factors, 1.8-inches and below, were discontinued around 2010. The cost of solid-state storage (NAND), represented by Moore's law ,

6834-555: The late 1990s, Israel was second only to the US in private equity as a share of the general economy. The high tech sector in Israel, known as Silicon Wadi , which earned Israel the nickname - Start-up Nation , was ranked the 4th leading startup ecosystem in the world by Startup genome with a value of $ 253billion in 2023. Europe is lagging behind in R&D investments from the past two decades. The target of 3% of gross domestic product (GDP)

6936-571: The latter of which is an enterprise oriented, upgraded version of the BT-200 with stereoscopic cameras. The company also was the first to release consumer smartglasses with transparent optics, which were popular with drone pilots for providing a first-person view while still being able to see the drone in the sky. In 2016, Epson presented the large-format SureColor SC-P10000 ink printer; it prints with inks in ten colours on paper up to 44 inches (1.1 m) wide. To control its printers, Epson introduced

7038-444: The magnetization of the material passing immediately under it. In modern drives, there is one head for each magnetic platter surface on the spindle, mounted on a common arm. An actuator arm (or access arm) moves the heads on an arc (roughly radially) across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins. The arm is moved using a voice coil actuator or, in some older designs,

7140-594: The manufacture of some of its high-end watches (Seiko Astron, Grand Seiko, Credor, etc) to Epson. The company makes some of Seiko's highest-grade watches at the Micro Artist Studio inside its Shiojiri Plant in Shiojiri , Nagano . Beside Seiko timepieces, Epson develops, designs, manufactures, markets, and sells watches under its own brands such as Trume, Orient , and Orient Star. In 2004, Epson introduced their R-D1 (the first digital rangefinder camera on

7242-422: The manufacturing of the read/write heads to increase the strength of the magnetic field created by the heads. In 2004, a higher-density recording media was introduced, consisting of coupled soft and hard magnetic layers. So-called exchange spring media magnetic storage technology, also known as exchange coupled composite media , allows good writability due to the write-assist nature of the soft layer. However,

7344-522: The market), which supports the Leica M mount and Leica M39 mount lenses with an adapter ring. Because its sensor is smaller than that of the standard 35 mm film frame, lenses mounted on the R-D1 have a field of view 1.53 times as wide as that of the standard 35 mm camera. In 2006, the R-D1 was replaced by the R-D1s, a cheaper version with identical hardware. Epson has released a firmware patch to bring

7446-420: The most commonly used operating systems report capacities in powers of 1024, which results in a smaller number than advertised. Performance is specified as the time required to move the heads to a track or cylinder (average access time), the time it takes for the desired sector to move under the head (average latency , which is a function of the physical rotational speed in revolutions per minute ), and finally,

7548-409: The needs of consumers and the potential niche market of a new product. If the development is technology driven, R&D is directed toward developing products to meet the unmet needs. In general, research and development activities are conducted by specialized units or centers belonging to a company, or can be out-sourced to a contract research organization, universities , or state agencies. In

7650-559: The norm in most computer installations and reached capacities of 300 megabytes by the early 1980s. Non-removable HDDs were called "fixed disk" drives. In 1963, IBM introduced the 1302, with twice the track capacity and twice as many tracks per cylinder as the 1301. The 1302 had one (for Model 1) or two (for Model 2) modules, each containing a separate comb for the first 250 tracks and the last 250 tracks. Some high-performance HDDs were manufactured with one head per track, e.g. , Burroughs B-475 in 1964, IBM 2305 in 1970, so that no time

7752-478: The pandemic report spending a big portion of their expenditure in 2020 on software, data, IT infrastructure, and website operations. A 2021/2022 survey found that one in every seven enterprises in the Central, Eastern and South Eastern regions (14%) may be classed as active innovators — that is, firms that spent heavily in research and development and developed a new product, process, or service — however this figure

7854-534: The platters, increasing areal density. Normally hard drive recording heads have a pole called a main pole that is used for writing to the platters, and adjacent to this pole is an air gap and a shield. The write coil of the head surrounds the pole. The STO device is placed in the air gap between the pole and the shield to increase the strength of the magnetic field created by the pole; FC-MAMR technically doesn't use microwaves, but uses technology employed in MAMR. The STO has

7956-401: The production of robots. In July 2003, a Netherlands -based consumer association advised its 640,000 members to boycott Epson inkjet printers. The organisation alleged that Epson customers were unfairly charged for ink they could never use. Later that month, however, the group retracted its call for a nationwide boycott and issued a statement conceding that residual ink left in Epson cartridges

8058-514: The program was to help improve sales, improve retail sales reps' knowledge of Epson products, and to address Epson customer service in a retail environment. Reps were assigned on weekend shifts, typically around 12–20 hours a week. Epson started the Weekend Warrior program with TMG Marketing (now Mosaic Sales Solutions), and later with Keystone Marketing Inc, then returned to Mosaic, and switched again to Campaigners Inc. on June 24, 2007 after

8160-416: The revenue of hard disk drives as of 2017 . Though SSDs have four to nine times higher cost per bit, they are replacing HDDs in applications where speed, power consumption, small size, high capacity and durability are important. As of 2019 , the cost per bit of SSDs is falling, and the price premium over HDDs has narrowed. The primary characteristics of an HDD are its capacity and performance . Capacity

8262-666: The sale of printers, copiers and multifunction devices amounted to 15.20 percent. In September 2015, Epson debuted the ET-4550 printer, which enables the user to pour ink into separate inkwells from ink bottles instead of cartridges. Epson is also involved in the smartglasses market. Since 2016, the company has three different models: the Moverio BT-100, the Moverio BT-200, and the Moverio Pro BT-2000,

8364-427: The speed at which the data is transmitted (data rate). The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, and 2.5-inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as SATA (Serial ATA), USB , SAS ( Serial Attached SCSI ), or PATA (Parallel ATA) cables. The first production IBM hard disk drive, the 350 disk storage , shipped in 1957 as

8466-438: The stack of disk platters when the drive was powered down. Instead, the heads were allowed to "land" on a special area of the disk surface upon spin-down, "taking off" again when the disk was later powered on. This greatly reduced the cost of the head actuator mechanism, but precluded removing just the disks from the drive as was done with the disk packs of the day. Instead, the first models of "Winchester technology" drives featured

8568-490: The strength of the correlation between R&D spending and productivity in low-tech industries is less than in high-tech industries, studies have been done showing non-trivial carryover effects to other parts of the marketplace by low-tech R&D. Business R&D is risky for at least two reasons. The first source of risks comes from R&D nature, where R&D project could fail without residual values. The second source of risks comes from takeover risks, which means R&D

8670-450: The swing arm actuator design to make possible the compact form factors of modern HDDs. As the 1980s began, HDDs were a rare and very expensive additional feature in PCs, but by the late 1980s, their cost had been reduced to the point where they were standard on all but the cheapest computers. Most HDDs in the early 1980s were sold to PC end users as an external, add-on subsystem. The subsystem

8772-439: The table above. Applications expanded through the 2000s, from the mainframe computers of the late 1950s to most mass storage applications including computers and consumer applications such as storage of entertainment content. In the 2000s and 2010s, NAND began supplanting HDDs in applications requiring portability or high performance. NAND performance is improving faster than HDDs, and applications for HDDs are eroding. In 2018,

8874-400: The thermal stability is determined only by the hardest layer and not influenced by the soft layer. Flux control MAMR (FC-MAMR) allows a hard drive to have increased recording capacity without the need for new hard disk drive platter materials. MAMR hard drives have a microwave generating spin torque generator (STO) on the read/write heads which allows physically smaller bits to be recorded to

8976-475: The top and bottom of the coil produce radial forces that do not rotate the head. The HDD's electronics controls the movement of the actuator and the rotation of the disk and transfers data to/from a disk controller . Feedback of the drive electronics is accomplished by means of special segments of the disk dedicated to servo feedback. These are either complete concentric circles (in the case of dedicated servo technology) or segments interspersed with real data (in

9078-491: The total number of errors in the entire HDD fixed by ECC (although not on all hard drives as the related S.M.A.R.T attributes "Hardware ECC Recovered" and "Soft ECC Correction" are not consistently supported), and the total number of performed sector remappings, as the occurrence of many such errors may predict an HDD failure . The "No-ID Format", developed by IBM in the mid-1990s, contains information about which sectors are bad and where remapped sectors have been located. Only

9180-433: The usual filtered air. Since turbulence and friction are reduced, higher areal densities can be achieved due to using a smaller track width, and the energy dissipated due to friction is lower as well, resulting in a lower power draw. Furthermore, more platters can be fit into the same enclosure space, although helium gas is notoriously difficult to prevent escaping. Thus, helium drives are completely sealed and do not have

9282-499: The volume of storage produced ( exabytes per year) for servers. Though production is growing slowly (by exabytes shipped ), sales revenues and unit shipments are declining, because solid-state drives (SSDs) have higher data-transfer rates, higher areal storage density, somewhat better reliability, and much lower latency and access times. The revenues for SSDs, most of which use NAND flash memory , slightly exceeded those for HDDs in 2018. Flash storage products had more than twice

9384-520: Was about the size of three large refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes per module. Access time was about a quarter of a second. Also in 1962, IBM introduced the model 1311 disk drive, which was about the size of a washing machine and stored two million characters on a removable disk pack . Users could buy additional packs and interchange them as needed, much like reels of magnetic tape . Later models of removable pack drives, from IBM and others, became

9486-578: Was coined by joining the initials EP (Electronic Printer) and the word son , making "Epson" mean "Electronic Printer's Son". In April of the same year, Epson America Inc. was established to sell printers for Shinshu Seiki Co. In June 1978, the TX-80 (TP-80) , an eighty-column dot matrix printer , was released to the market and was mainly used as a system printer for the Commodore PET computer. After two years of further development, an improved model,

9588-477: Was destined to fund basic research. According to National Science Foundation in U.S., in 2015, R&D expenditures performed by federal government and local governments are 54 and 0.6 billions of dollars. The federal research and development budget for fiscal year 2020 was $ 156 billion, 41.4% of which was for the Department of Defense ( DOD ). DOD's total research, development, test, and evaluation budget

9690-643: Was founded in May 1942 by Hisao Yamazaki, a local clock shop owner and former employee of K. Hattori , in Suwa, Nagano . Daiwa Kogyo was supported by an investment from the Hattori family (founder of the Seiko Group) and began as a manufacturer of watch parts for Daini Seikosha (currently Seiko Instruments ). The company started operation in a 230-square-metre (2,500 sq ft) renovated miso storehouse with 22 employees. In 1943, Daini Seikosha established

9792-427: Was lost physically moving the heads to a track and the only latency was the time for the desired block of data to rotate into position under the head. Known as fixed-head or head-per-track disk drives, they were very expensive and are no longer in production. In 1973, IBM introduced a new type of HDD code-named " Winchester ". Its primary distinguishing feature was that the disk heads were not withdrawn completely from

9894-528: Was meant to be reached by 2020, but the current amount is below this target. This also causes a digital divide among countries since only a few EU Member States have R&D spending. Research and innovation in Europe are financially supported by the programme Horizon 2020 , which is open to participation worldwide. A notable example is the European environmental research and innovation policy , based on

9996-452: Was necessary for the printers to function properly. Epson designed ink to be left in the cartridges (having done so ever since the introduction of piezoelectric print heads) due to the way the capping mechanism worked. If the capping mechanism dries out, then the heads risk getting clogged, necessitating expensive repairs. The reason that the Dutch consumer association retracted their statement

10098-513: Was not sold under the drive manufacturer's name but under the subsystem manufacturer's name such as Corvus Systems and Tallgrass Technologies , or under the PC system manufacturer's name such as the Apple ProFile . The IBM PC/XT in 1983 included an internal 10 MB HDD, and soon thereafter, internal HDDs proliferated on personal computers. External HDDs remained popular for much longer on

10200-508: Was roughly $ 108.5 billion. Israel is the world leader in spending on R&D as a percentage of GDP as of 2022, spending 6.02%. According to CSIS, During the 1970s and 1980s Israel initially built up Israel's research infrastructure through various programs, often in the defence industry. In 1984, a law for Encouragement of Research and Development in Industry encouraged the commercial sector to invest in R&D in Israel as well as empowered

10302-590: Was that, as pointed out, Epson had made a statement regarding how many pages (at usually a 5% coverage of an A4 sheet of paper ) each cartridge could sustain for printing. Nonetheless, Epson America, Inc. settled a class action lawsuit brought before the Los Angeles Superior Court . It did not admit guilt, but agreed to refund $ 45 to anyone who purchased an Epson inkjet printer after April 8, 1999 (at least $ 20 of which must be used at Epson's e-Store). According to IDG News Service , Epson filed

10404-408: Was the norm. As of November 2019 , the platters in most consumer-grade HDDs spin at 5,400 or 7,200 rpm. Information is written to and read from a platter as it rotates past devices called read-and-write heads that are positioned to operate very close to the magnetic surface, with their flying height often in the range of tens of nanometers. The read-and-write head is used to detect and modify
