Interrupt timing constriants under a multitasking OS - existing DOS drivers
apparently work by polling and need vitually all the CPU time.

I've heard that there do exist such things but that they don't actually work.
(Or rather they do so much backspacing that a single use will take a tape
outside its design life - I'm not sure I belive this but it's what

Yep, once the hard bit (the low level driver) is done this should be a
relatively easy operation for a non-streaming tape. I've always had my
doubts about the efficacy of random access tape systems though.

You're not the only one - there are several people (including myself) who
have expressed an interest in "having a go". I think we should all subscribe
to the linux-activists tape channel (or possibly create a new channel). We
don't want too much wasted duplication of effort.
