I believe it is. And, I have no data about it. Beware, it may
be another in the Aiwa/Onstream/Sony family that is NOT a standard
ATAPI tape drive. Do the specs mention "TRAVAN" ? If so, it's probably
ok ...

I have no information on this, and apparently nobody has stepped up to
answer it.

Of course you can write multiple files to the tape. That's what the
'n' devices are for. It's just the "exotic" mtops that haven't
been implemented. And, this is a perfect project for somebody who wants
to pick it up :-)

Travan is an industry standard for higher density hard formatted
QIC tapes.

With a well-tuned configuration, you'll get about 500KB/s throughput
to a parallel port tape drive with the pt driver. If that's not good
enough, spend more money on a SCSI solution.
