As the OP didn't specify the overall goal, one can't say.

One can store all the information, including block boundaries,
on the USB, then recreate an ANSI tape on another system, or
directly read a virtual tape image on another system.
In those cases, the intermediate system doesn't need to know
anything about ANSI to read it "properly."
