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 phrase cassette tape is ambiguous in that there is no common dictionary definition [1] [2] [3] so depending upon usage it has many different meanings, as for example any one the one of 106 different types of audio cassettes, [4] video cassettes [5] or data cassettes [6] listed at The Museum of Obsolete Media.
Gene cassette, certain vectors that are normally used to confer a selectable marker on an organism; Cassette cogset, a set of multiple sprockets on a bicycle; Cassette munition, a term for Cluster munition common in Slavic languages, particularly Ukrainian (касетні боєприпаси) Cassette toilet, a type of portable camping toilet
The IEC reference tape bias definition is: Using the relevant IEC reference tape and heads according to Ref. 1.1, the bias current providing the minimum third harmonic distortion ratio for a 1 kHz signal recorded at the reference level is the reference bias setting.
The thickest tape normally used in cassettes is about 16-18 μm in thickness, and is used in C60 cassettes and in shorter lengths such as the C46. As the standard tape speed for a compact cassette is 1 + 7 ⁄ 8 ips (4.75 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 ...
A key element of the cassette's success was its use in in-car entertainment systems, where the small size of the tape was significantly more convenient than the competing 8-track cartridge system. Cassette players in cars and for home use were often integrated with a radio receiver. In-car cassette players were the first to adopt automatic ...
Reel-to-reel preceded the development of the compact cassette with tape 0.15 inches (3.8 mm) wide moving at 1 + 7 ⁄ 8 inches per second (4.8 cm/s). By writing the same audio signal across more tape, reel-to-reel systems give much greater fidelity at the cost of much larger tapes.
Visualization of the magnetic field on a stereo cassette containing a 1 kHz audio tone. Individual high-frequency magnetic domains are visible. Tape bias is the term for two techniques, AC bias and DC bias, that improve the fidelity of analogue tape recorders. DC bias is the addition of direct current to the audio signal that is being recorded.
