As far as I know the format of a Teledisk archive file has never been 
officially documented. IMHO that makes it totally unsuitable to use as a 
portable archibe format. And I don't think it covers things like GCR 
recording, sectors with headers recorded at a different density to the 
data, hard sectored disks, and so on.

Only if you happen to run an MS-DOS PC.
