fwiw, I made my own format when I archived all my old tapes. A very simple one:
- I read the tape record by record
- The output disk file contains a 4-byte integer in big endian format,
followed by one record.
- The 4-byte integer contains the physical record size as read from the tape.
- Then another 4-byte value plus a new record, and so on.
- End-of-file markers are encoded by using 0 as the value for the
4-byte integer, with no record following (logically enough).
