Tape imaging

Now, now, no need to be harsh.  I daresay this format was intended for
purposes somewhat different from .tap's and thus its tradeoffs were
made differently.

I invented a similar slightly different format myself, once (it was to
represent tapes in a software-simulated tape drive; it was much like
the format whose description I cut, above, except that each record had
its length after as well as before it, to make backward skips easy -
something not important and not worth spending storage space on if
you're just trying to archive existing tapes' data).

> how did you handle unreadable blocks.

Quite possibly not at all, since it appears to have been intended for
archiving readable tapes.
