Digital Compact Cassette (DCC), a magnetic tape sound recording format introduced by Philips and Matsushita in late 1992 and marketed as the successor to the standard analog Compact Cassette; NT (cassette), a small cassette tape created by Sony that was smaller than a Picocassette only used for dictation machines but had plans to be used in music
[2] [3] Through the 1980s and 1990s, Sony created many versions and variations in the cassette tape Walkman line [4] such as the DD series and WM series. Below is an incomplete list of cassette tape based Walkman models. Sony Walkman TPS-L2, from 1979. Sony Walkman WM-F15, released 1984. Sony Walkman WM-28, early 1980s Sony Walkman WM-F77 ...
The microcassette was beaten to market by the Mini-Cassette, introduced by Philips in 1967. The mini-cassette is almost identical in appearance and dimensions to the microcassette, however it has thicker cogs for its reels and a slightly wider cassette. The mini-cassette, despite making it to market first, was less successful than the ...
As the standard tape speed for a compact cassette is 1 + 7 ⁄ 8 inches per second (4.762 cm/s) and a C60 cassette records 30 minutes per side, a C60 cassette in theory holds 281 + 1 ⁄ 4 ft (85.73 m) of tape. In practice there is some variation, for example Maxell quote their C60s as being 90 m (300 ft) in length.
The Compact Cassette, also commonly called a cassette tape, [2] 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.
The development of the videocassette followed other replacements of open-reel systems with a cassette or cartridge in consumer items: the Stereo-Pak 4-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 motion picture film cartridge in 1966.
Equal to 8-track tape and Stereo-Pak, the tape runs at a standard speed of 3.75 inches per second (IPS). [5] This is double the speed of the Compact Cassette and half of the top speed of consumer reel-to-reel tape recorders, which usually offer both 3.75 IPS and 7.5 IPS speeds.
The technical reference for the IBM PC 5150 specifies that the WRITE-BLOCK routine turns on the cassette drive motor and transforms each byte into bits.A (1) bit corresponds to a 1.0 ms timer period, (0) bit corresponds to 0.5 ms, which results in a recording speed of 1000 - 2000 bit/s.
