Digital Audio Stationary Head, which competed against ProDigi when the format was available in the mid-1980s through the early 1990s. Audio was digitally recorded linearly on the tape and is guarded by a powerful
error correction scheme of
cyclic redundancy checks to ensure integrity of the signal even if data is lost during playback. Prodigi recorders were available in 2-track variations, which used 1/4" tape; 32-track variations, which used 1" tape, and a 16-track version using 1/2" tape. All of the machines require the use of

Otari DTR-900 (an X-850, rebadged for Otari).
Mitsubishi and Otari collaborated on the design of the X-850 and X-880. The tape transport of both machines was derived from the Otari MTR90 Mk II, modified to handle 1" tape. Some mechanical parts were interchangeable between the X-850 and MTR90, the PC cards in the transport control section were manufactured by Otari and with two exceptions (the capstan servo and master CPU cards) were interchangeable between the Mitsubishi and Otari machines. The section of the X-850 service manual concerning transport adjustments was a verbatim reprint of the corresponding section of the MTR90 service manual.

X-80
The Mitsubishi X-80 2-track 1/4 inch digital recorder from 1980 predated the ProDigi format and has many similarities, although it used an unusual 50.4 kHz sample rate, and is not directly compatible. However, Mitsubishi did build the capability to play back tapes created on an X-80 into the X-86 series machines. Only 200 X-80's were manufactured.
