Exactly. I'm starting to see a trend with some brands of floppies
more than 25 years old where the oxide is starting to separate from
the substrate, leading to fouled heads and "see through" tracks.
Mostly on Wabash brand floppies currently, although a few off-brands
such as "Precision" seem to also be showing this behavior.
Time to get 'em archived.
