that is real simple. You have a physical section that says it is a sequential block of
data. You point to the data block that has a length. End of image file in the case.
If you know nothing about the format, all you can do is save a sequential data block.
I would still separate the two out for strictly consistency sake, so you can get the data
easiliy to analyze. Once anlyzed, the a new image file could be generated with more info.

This is supposed to be an archive format which would in my view preclude
getting data from the outside world. My only other concern as I have
stated before was that data should not be an integral part of the media.
If a device happens to be a tape drive, the data on the tape still
separates into "file" type data and overhead data required for the tape
physical format. Enbedding the "file" tyupe data inside of the physical
format makes the data inaccessible without special knowledge.
Steve,
What if you don't know what a tape you are archiving contains in the first
place? What if you just want to preserve it in case someone else in the
future can figure it out?
