Blu-ray Discs
Blu-ray (Blu-ray Disc or BD) is a Digital media, digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X and Series S, Xbox Series X. The name refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs, resulting in an increased capacity. The polycarbonate disc is in diameter and thick, the same size as DVDs and Compact disc, CDs. Conventional (or "pre-BDXL") Blu-ray discs contain 25gigabyte, GB per layer, with dual-layer discs (50GB) being the industry standard for fe ...

Imation
GlassBridge Enterprises, Inc., formerly Imation Corporation, is an American holding company. Through its subsidiary, Glassbridge focuses primarily on investment and asset management. The company was founded in 1996 under its original name of Imation as a spin-off of 3M's data storage and imaging business. Prior to the name change, Imation had three core elements: traditional storage (magnetic tape and optical products), secure and scalable storage (data backup, data archive and data security for small and medium businesses) and what the company calls "audio and video information" products. In January 2017, the company announced a change of name and direction, completing its move away from the data storage business towards being focused on asset management and strategic investment and rebranding itself as Glassbridge Enterprises. The Imation brand was sold off later that year to O-Jin Corporation Co., a Korean company who have since licensed its use to other businesses, bu ...

Compact Cassette
The Compact Cassette, also commonly called a cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips, the Compact Cassette was released in August 1963. Compact Cassettes come in two forms, either containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed—for example the Microcassette—the generic term ''cassette tape'' is normally used to refer to the Compact Cassette because of its ubiquity. From 1983 to 1991 the cassette tape was the most popular audio format for new music sales in the United States. Compact Cassettes contain two miniature spools, between which the magnetically coated, polyester-type plastic film (magnetic tape) is passed and wound—essentia ...

Nikkei 225
The Nikkei 225, or , more commonly called the ''Nikkei'' or the ''Nikkei index'' (), is a stock market index for the Tokyo Stock Exchange (TSE). It is a price-weighted index, operating in the Japanese yen, Japanese Yen (JP¥), and its components are reviewed twice a year. The Nikkei 225 measures the performance of 225 highly capitalised and liquid publicly owned companies in Japan from a wide array of industry sectors. Since 2017, the index is calculated every five seconds. It was originally launched by the Tokyo Stock Exchange in 1950, and was taken over by the ''The Nikkei, Nihon Keizai Shimbun'' (''The Nikkei'') newspaper in 1950 in Japan, 1970, when the Tokyo Exchange switched to the TOPIX, Tokyo Stock Price Index (TOPIX), which is weighed by market capitalisation rather than stock prices. History The Nikkei 225 began to be calculated on 7 September 1950, retroactively calculated back to 16 May 1949, when the average price of its component stocks was 176.21 yen. Since July ...

CD-R
CD-R (Compact disc-recordable) is a digital media, digital optical disc data storage device, storage format. A CD-R disc is a compact disc that can only be Write once read many, written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs. History Originally named CD Write once read many, Write-Once (WO), the CD-R specification was first published in 1988 by Philips and Sony in the Rainbow Books, Orange Book, which consists of several parts that provide details of the CD-WO, CD-MO (Magneto-Optic), and later CD-RW (Re Writable). The latest editions have abandoned the use of the term ''CD-WO'' in favor of ''CD-R'', while ''CD-MO'' was rarely used. Written CD-Rs and CD-RWs are, in the aspect of low-level encoding and data format, fully compatible with the audio CD (''Red Book'' CD-DA) and data CD (''Yellow Book'' CD-ROM) standards. The Yellow Book standard for CD-ROM only speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrite (magnet)
A ferrite is one of a family of iron oxide-containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be Magnetization, magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are not electrically electrical conductor, conductive, making them useful in applications like magnetic cores for transformers to suppress eddy currents. Ferrites can be divided into two groups based on their magnetic coercivity, their resistance to being demagnetized: "Hard" ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors. "Soft" ferrites have low coercivity, so they easily change their magnetization and act as conductors of magnetic fields. They are used in the electronics industry to make efficient magnetic cores called ferrite cores for high-frequency inductors, transfo ...

Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

IEEE
The Institute of Electrical and Electronics Engineers (IEEE) is an American 501(c)(3) organization, 501(c)(3) public charity professional organization for electrical engineering, electronics engineering, and other related disciplines. The IEEE has a corporate office in New York City and an operations center in Piscataway, New Jersey. The IEEE was formed in 1963 as an amalgamation of the American Institute of Electrical Engineers and the Institute of Radio Engineers. History The IEEE traces its founding to 1884 and the American Institute of Electrical Engineers. In 1912, the rival Institute of Radio Engineers was formed. Although the AIEE was initially larger, the IRE attracted more students and was larger by the mid-1950s. The AIEE and IRE merged in 1963. The IEEE is headquartered in New York City, but most business is done at the IEEE Operations Center in Piscataway, New Jersey, opened in 1975. The Australian Section of the IEEE existed between 1972 and 1985, after which it s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DVD Recordable
DVD recordable and DVD rewritable are a collection of optical disc formats that can be written to by a DVD recorder and by computers using a DVD writer. The "recordable" discs are write-once read-many (WORM) media, where as "rewritable" discs are able to be erased and rewritten. Data is written (" burned") to the disc by a laser, rather than the data being "pressed" onto the disc during manufacture, like a DVD-ROM. Pressing is used in mass production, primarily for the distribution of home video. DVD±R (also DVD+/-R, or "DVD plus/dash R") is a shorthand term for both DVD+R and DVD-R formats. Likewise, the term DVD±RW refers to both rewritable disc types, the DVD+RW and the DVD-RW. DVD±R/W (also written as, DVD±R/RW, DVD±R/±RW, DVD+/-RW, DVD±R(W) and other arbitrary ways) handles all common writable disc types, but not DVD-RAM. A drive that supports writing to all these disc types including DVD-RAM (but not necessarily including cartridges or 8cm diameter discs) is referr ...

Videotape
Videotape is magnetic tape used for storing video and usually Sound recording and reproduction, sound in addition. Information stored can be in the form of either an analog signal, analog or Digital signal (signal processing), digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram. Because video signals have a very high Bandwidth (signal processing), bandwidth, and Tape head, stationary heads would require extremely high tape speeds, in most cases, a helical scan, helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a Linear motion, linear method of storing information and thus imposes delays to access a portion of the tape that is not already against the heads. The early 2000s saw the introduction and rise to prominence of high-q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
