<cringe> that would be 9600 bit per inch GCR format 9-track tape, don't you think? </cringe>
At least in the IBM world, the options for 7-track were 200/556/800 bpi with even or odd parity, and mode=normal/data converter/translator. 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. -- Valdis Kletnieks Operating Systems Analyst Virginia Tech

-- Hello; Real Men use punched paper tape to store programs and load the boot block, after toggling its binary location on the system console register :) The Gods Who Walk Among Us program in machine code by toggling it in at the console. (I still have some punched paper tape somewhere. I remember feeling impressed when I graduated to punched cards. They didn't tend to crack if you had a string of all bits set to one.) On the other hand, I did tens of thousands of lines of code on IBM punched cards and I never once recall a bug caused by a chad, hanging or otherwise.
