3.3.1, qic 24, 600 ft. tapes, and distcp

[Bruno Pape]

Hello Magnetic Media types,

I was planning on making some copies of my 3.3.1 tape to ship out
to some people who need it.  But I seem to have run into a small
problem.  It seems that 3.3.1 is slightly less than 70MB which is
somewhat greater than the 60MB I can write on a 600 ft. tape in
qic 24 format.  Am I missing something or is 3.3.1 on a 700 foot
tape.

Thanks for any insight,

Bruno
