For 9-track the options are 800 NRZI, 1600 PE, and 6250 GCR. I still have 21 9-track tapes in my office that I need to do something with, as our last system with 3420-style round tapes is being decomissioned in the next few months.
Let's see... 6250 bpi * 12 in/ft * 1600 ft == 120M, if I haven't miscounted decimal places. So you can fit 5 tapes per CD-ROM, and save a lot of space. --Steve Bellovin
