This may not be close enough to what you're
looking for, but DEC put
the RT11 filesystem on TU58 tapes. They could be used just like very
slow floppies. The tape drive took care of locating logical blocks on
the tape, essentially providing a block type device to the computer.
Very different.
The TU58 behaves like a disk, not a tape.
Anyway, ANSI is a "file system" for tapes. A "normal" file system
will
be very hard, since that would require the ability to rewrite existing
blocks in the middle of the tape, which is a scary thing to try.
