    What I have done in the past was to analyze the structure of the boot tapes
with a utility
called tapemap, copied the individual files to disk with dd, then copied them
back out to a duplicate tape. This could go tape to tape, of course. Tapemap is
pretty simple. It reads each 
record of each file, and finds the largest  record, which it reports as the
blocksize of that file.
I can send the source and man page via mail if anyone needs it.
