Well, I finally got around to attempting to re-spool this stupidly
designed tape.

Your description sounds like a different tape than what I was dealing
with.  The tape did not come off of either spool but was instead attached
onto both spools.

At any rate, the stupid tensioning belt (whatever its called) broke on me.
Oh well, fuck that tape.  I'll try to read it anyway (is the tensioning
belt necessary?)  I also noticed numerous spots on the the tape where the
oxide had flaked off, so any re-attempt may well be futile.  Whoever
designed these tapes is a moron.  I can't imagine how impossibly expensive
it must've been to manufacture them.

I hate computers.
