Not really. An ANSI tape consists merely of blocks and tape marks. Some 
of the blocks are quite small and contain the filenames, labels, etc., 
and some contain data. One merely has to read them, store each block at 
its correct size, and store the mini-blocks that make up the tape marks. 
ANSI is irrelevant; that simply dictates the size and contents of the 
blocks.

Oh, and I've done it. A long time ago, mind.
