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.
