Something is confused - you should be able to access the images sequentially
simply by issuing repeated tar commands using the non-rewind device.  You
might check the minor device numbers between the rewind and no-rewind device
to make sure you're getting what you expect.

Also, if you mucking around with TK50's expect a lot of tedious back-and-forth
on the tape, but then I'd expect your fsf's to skip files rather then the
"rewinding" you suggest.
