What is Digital Compact Cassette?

It competed with the [[Minidisc]] and the [[Digital Audio Tape]] (DAT), but neither format could replace the compact cassette. It was marketed as a cheaper alternative to DAT. Equipment for the digital compact cassette was able to playback [[Analog signal|analog]] compact cassettes as well; recording could only be done to DCC, though. A DCC tape is similar in appearance to a regular cassette, except that it has reel access holes on only one side, and has a shutter covering both the tape and reel access holes, similar to the shutter on a [[floppy disk]]. This protects the tape and also prevents it from being accidentally inserted into an analog cassette deck. Some DCC players could also play analog compact cassettes (DAT players couldn't do so), these players would detect the cassette type from the presence or absence of the shutter cover. Unlike DAT, DCC uses [[lossy data compression]]. This means that the copy of the data is not identical to the original. Audio data could be compressed to about 25% of its original size. The main problem of the format was tied to handling: Finding a song in the middle of a 90 minute tape takes several minutes. With Minidisc it is instantaneous. Minidisc allows to [[delete]] or move tracks, features which the digital compact cassette cannot offer. Even though some of the features were addressed (like rewinding a 90 minute tape in less than a minute), the format never gained much [[market share]]. The compression format used by DCC is based on MP1, which came before [[MP3]]. The [[CD-R]], which is compatible with standard CD players, eventually replaced both DCC and MiniDisc for home audio recording. T
