Yes, I wrote them myself, back when I was young and naive and didn't
really understand how the technology worked. I wrote out each tape as
a series of tar images, and followed each one with an EOF marker
with mt, not realizing that tar was implicitly writing an EOF when
it finished writing its stuff. So each tapes actually contains a sequence
of the form
tar-image zero-length-file tar-image zero-length-file ...
If I recall correctly, the density was something like 6250 or 6280
or something similar.
