dd works on tapes, but unless the tape can be recreated from the byte
stream, it's not what you want.

I'd suggest copytape, myself.  It's a way of encapsulating streams of
records into streams of bytes, and a program to read tapes and write
bytestreams and vice versa.

There's a version of it up for anonymous ftp from
ftp.rodents.montreal.qc.ca (in /mouseware/local-src/copytape/); I don't
know what other versions may be kicking around....
