Actually,
DEC's tape drives were abysmal in design (not counting the
DECtapes which were really reel-to-reel disk drives.
Yes, DECtapes are very cool. DLTs are pretty nice too; they FINALLY
fixed the TK50 after a few iterations! ;)
The TK50 was not so great; the TK70 was much more reliable. I don't have
any experience with the TZ30 (although I do have one somewhere). The Tx85,
Tx86, Tx87, Tx88, and Tx89 all seem to be exceptionally reliable (along with
the equivalent DLTx000 drives). I used to use DAT at home. Now I use a
DLT4700 system.
