It's John Wilson's tape image file format.
A data record consists of a four byte record length, the data,
then another copy of the record length. The record length is stored
in little-endian byte order.
A tape mark is fourbytes of zeros.
There are no extra padding bytes to force any alignment.
Bob Subnik's SIMH tape image file format is similar except that it
uses 16-bit alignment. SIMH comes with utilities to convert the
formats.
There are also some simple tape image utilities at:
