Digital Tape Recording System (DTRS) is a signal recording and playback medium developed by TASCAM, a division of the TEAC Corporation, that was stored on Hi8 video cassettes.
It allowed up to 108 minutes of continuous digital multitrack recording on a single tape.
It also allowed multiple DA-88 devices to be combined to record 16 or more tracks.
[3] The first models in the series (the TASCAM DA-88, DA-38, DA-98 and Sony PCM-800) recorded at 16-bit resolution.
[6]Because of its reliability and durability, the DA-88 and its subsequent fellow units continue to be used by aficionados.
