The DCC (Digital Compact Cassette) was published by Philips and Matsushita in 1992. The cassette is the same size as the original Compact Cassette is. DCC-recorders are backwards compatible in such a way, that they can play analog Compact Cassettes.

A DCC-recorder has a stationary record head. The digital data is recorded in nine narrow tracks on one half of the tape. The tape is played into both directions, but the user doesn't need to turn the DCC cassette. There were differences in portable models. The longest DCC duration is 120 minutes. The tape is protected behind a metal cover, when it is not in the recorder. The tape speed and the tape width are the same as in the Compact Cassette. The active layer material of the tape is the same as in digital video tapes, very often chromium dioxide.

Sampling rates for the DCC are
32, 44.1 ja 48 kHz, when recording from the digital inputs. From analog input the samplig rate is 44.1 kHz. The DCC uses PASC data reduction with a bitrate of 1,4 MBit/s.

DCC was discontinued in 1996, so the format lasted only for a couple of years.
