Probably not.  I don't know the uncorrected error rates for DAT audio and
data recording technologies, but the error requirements for recording
digital data are far more stringent than for recording audio.

Think about it - one incorrect bit can cause a multimegabyte file to be
unusable.  One incorrect bit in a few megabytes of an audio stream is likely
to be unnoticed.

In my previous place of employment, our department went through several DAT
machines, and the admin was constantly cursing at them.  When I was
considering a tape backup for my own use, I asked for a recommendation from
someone who works in the media division of 3M (they make tapes in several
digital formats).  She recommended Travan, which is an older technology than
DAT, but (according to her) much more reliable.  I used a Travan 4 drive for
several years without any glitches.  Currently I am backing up to hard disk
and CD-R (Mitsui Gold).
