Sounds like the oxide is crapped out and starting to come off [on your
heads!]. I ran across the same thing with a big box of HP
cassettes--only about 6 out of 50 or so were even remotely usable [and
they had been stored in the original storage boxes in reasonable
environmental conditions for the last 20 years]. Doesn't bode well for
the future of tape media.
