Microcassette
The Microcassette (often written generically as microcassette) is an audio storage medium, introduced by Olympus in 1969. It has the same width of magnetic tape as the Compact Cassette but in a cassette roughly one quarter the size. By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette but in a smaller package. History Microcassettes have mostly been used for recording voice. In particular, they are commonly used in dictation machines and answering machines. Microcassettes have also been used in computer data storage and to record music. For the latter purpose, devices for recording in stereo were produced in 1982 and, for higher fidelity, microcassettes using Type IV ("metal", i.e. coated with pure metal particles rather than oxide) tape were sold. This was an attempt by Olympus to cash in on the burgeoning Walkman market; one model, the Olympus SR-11, had a built-in radio and offered a stereo ...

Mini-cassette
The Mini-Cassette, often written minicassette, is a magnetic tape audio cassette format introduced by Philips in 1967. It is used primarily in dictation machines and was also employed as a data storage for the Philips P2000 home computer. As of August 2021, Phillips still produces mini-cassette players along with new mini-cassette tapes. Design Unlike the Compact Cassette, also designed by Philips, and the later Microcassette, introduced by Olympus, the Mini-Cassette does not use a capstan drive system; instead, the tape is propelled past the tape head by the reels. This is mechanically simple and allows the cassette to be made smaller and easier to use, but produces a system unsuited to any task other than voice recording, as the tape speed is not constant (averaging 2.4 cm/s) and prone to wow and flutter. However, the lack of a capstan and a pinch roller drive means that the tape is well-suited to being repeatedly shuttled forward and backward short distances as compa ...

Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, 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 in 1963, Compact Cassettes come in two forms, either already 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 always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge and ...

Picocassette
Picocassette is an audio storage medium introduced by Dictaphone in collaboration with JVC in 1985. The Picocassette was introduced to compete with the Microcassette, introduced by Olympus Corporation, Olympus, and the Mini-Cassette, by Philips. Size It is approximately half the size of the previous Microcassette, and was intended for highly portable Dictation machine, dictation devices. With a tape speed of 9 millimeters per second, each cassette could hold up to 60 minutes of dictation, May 27, 1985, ''Time.com'', Retrieved 2010-04-06 30 minutes per side. The signal-to-noise ratio was 35 Decibel, dB. The widest dimension of the picocassette was near 4.2 cm. See also |
Magnetic Cassette Tape
Magnetic tape cartridge and magnetic tape cassette both refer to a small plastic unit containing a length of magnetic tape on at least one reel. The unit may contain a second "take-up" reel or interoperate with such a reel in an associated tape drive. At least 142 distinct types have been known to exist. The phrase ''cassette tape'' is ambiguous in that there is no common dictionary definition so depending upon usage it has many different meanings, as for example any one the one of 106 different types of audio cassettes, video cassettes or data cassettes listed aThe Museum of Obsolete Media The phrase ''cartridge tape'' is also ambiguous with 36 different types of audio, video or data cartridges listed at The Museum of Obsolete Media. From time to time the terms tape cartridge and tape cassette are used to describe the same product. In current production are the Cassette tape, the LTO tape cartridge and the IBM 3592 tape cartridge. Audio * Analog based ** Cassette tape ...

Dictation Machine
A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print. It includes digital voice recorders and tape recorder. The name "Dictaphone" is a trademark of the company of the same name, but it has also become a common term for all dictation machines, as a genericized trademark. History Alexander Graham Bell and his two associates took Edison's tinfoil phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's Volta Laboratory in Washington, D.C.In 1879, and continued until they were granted basic patents in 1886 for recording in wax.Newville, Leslie JDevelopment of the Phonograph at Alexander Graham Bell's Volta Laboratory United States National Museum Bulletin, United States National Museum and the Museum of History and Technology, Washington, D.C., 1959, No. 218, Paper 5, pp.69-79.

Magnetic Tape
Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape could with relative ease record and playback audio, visual, and binary computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing. Since the early 1950s, magnetic tape has been used with computers to store large quantities of data and is still used for backup purposes. Magnetic tape begins to degrade after 10–20 years and therefore is not an ideal medium for long-term archival storage. Durability While good for short-term use, magnetic tape is highly prone to disintegration. Depending on the environment, this process may begin after 10–20 years. Over time, magnetic tape made in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philips
Koninklijke Philips N.V. (), commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions. The company was founded in 1891 by Gerard Philips and his father Frederik, with their first products being light bulbs. It currently employs around 80,000 people across 100 countries. The company gained its royal honorary title (hence the ''Koninklijke'') in 1998 and dropped the "Electronics" in its name in 2013, due to its refocusing from consumer electronics to healthcare technology. Philips is organized into three main divisions: Personal Health (formerly Philips Consumer Electronics and Philips Domestic Appliances and Personal Care), Connecte ...

Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Music
Underground music is music with practices perceived as outside, or somehow opposed to, mainstream popular music culture. Underground music is intimately tied to popular music culture as a whole, so there are important tensions within underground music because it appears to both assimilate and resist the forms and processes of popular music culture. Underground music may be perceived as expressing sincerity, intimacy, freedom of creative expression in opposition to those practices deemed formulaic or commercially driven. Notions of individuality non-conformity are also commonly deployed in extolling the virtue of underground music. There are examples of underground music that are particularly difficult to encounter, such as the underground rock scenes in the pre-Mikhail Gorbachev Soviet Union, in which has amassed a devoted following over the years (most notably for bands such as Kino). However, most underground music is readily accessible, although performances and recordings m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Music
Experimental music is a general label for any music or music genre that pushes existing boundaries and genre definitions. Experimental compositional practice is defined broadly by exploratory sensibilities radically opposed to, and questioning of, institutionalized compositional, performing, and aesthetic conventions in music. Elements of experimental music include indeterminate music, in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. Artists may also approach a hybrid of disparate styles or incorporate unorthodox and unique elements. The practice became prominent in the mid-20th century, particularly in Europe and North America. John Cage was one of the earliest composers to use the term and one of experimental music's primary innovators, utilizing indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using the term ''musique expérimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lo-fi Music
Lo-fi (also typeset as lofi or low-fi; short for low fidelity) is a music or production quality in which elements usually regarded as imperfections in the context of a recording or performance are present, sometimes as a deliberate choice. The standards of sound quality (fidelity) and music production have evolved throughout the decades, meaning that some older examples of lo-fi may not have been originally recognized as such. Lo-fi began to be recognized as a style of popular music in the 1990s, when it became alternately referred to as DIY music (from "do it yourself"). Harmonic distortion and " analog warmth" are sometimes confused as core features of lo-fi music. Traditionally, lo-fi has been characterized by the inclusion of elements normally viewed as undesirable in professional contexts, such as misplayed notes, environmental interference, or phonographic imperfections (degraded audio signals, tape hiss, and so on). Pioneering, influential, or otherwise significant a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
