DAT

 Digital Audio Tape. There are two formats: R-DAT which uses a rotating head assembly similar to a VCR, records diagonally across the tape, and includes a four-channel format which would permit recording of ambisonics; and the S-DAT which uses a stationary head and records several linear, parallel tracks of digital signals. There are no known commercial S-DAT products. The DAT standard format specifies a small cassette that provides up to two hours of 16-bit, linearsequential monauralPCM digital recording at a sampling rate of 32kHz, 44.1kHz, or 48kHz. Also called a DCAC, Digital Compact Audio Cassette. See also Digital Compact Cassette.
