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.

best regards, Steve Thatcher

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?
