Needed: 1 IBM 8" alignment disk.

I've got hundreds of diskettes over 20 years old, and NONE have been losing
emulsion. I've had some of the jackets crack, and I've had some of the ones
which have gotten wet along the way stick in their jackets so they wouldn't
rotate, but the emulsion on those which would rotate, I've never had flaking
of the emulsion. Maybe that's because it's really dry here in Denver.

If you clean your disk heads from time to time, you'll probably not build up
enough glutch to damage a diskette.
