Digital Compact Cassette: Describes an alternative to the traditional analog compact cassette developed by Philips and Matsushita in 1992. The Digital Compact Cassette was initially known internally as S-DATs (Static-heads Digital Audio Tape) (due to similarity to the professional THAT-recording system).
There are a number of advantages over conventional cassettes, e.g. B. the higher frequency range with 48 kHz DCC recordings from 20 - 22.000 Hz (the normal cassette only reached 18.000 Hz) and the signal-to-noise ratio of a DCC > 92 dB. The DCC also used a method for data reduction, viz PASC. PASC works similar to MPEG-1 and compresses the piece of music to a size of approx. 1:4.
