What is the difference between DAT,
DTRS, adat, MDM and DASH?
Tascam's DA-xx series machines are referred
to either as "DA-88's" (because it was the first in the series) OR, more
precisely, by the manufacturer's trade name for the Hi-8mm format, "DTRS"
(Digital Tape Recording System).
Tascam's DTRS and the Alesis "adat" formats
are both referred to as "MDM's" or Modular Digital Multitracks. The
adat uses Super-VHS "S-VHS" tape. Other Digital
Audio Tape machines include the 4 mm DAT format, which started life as
the "RDAT," the "R" being a reference to the "Rotating" head assembly.
There are also DASH (Digital Audio Stationary Head) machines, such as the
Sony 3324 and 3348, which primarily use 1/2-inch open reel tape.
Mitsubishi and 3M DASH machines use 1-inch tape.
