A few years ago many (including me) were using the Press On Labels

Didn't take long to find out they tended to WARP over time, making certain portions of the CD unreadable. I recovered data from many
by clamping between two other unuseable cds and placing in freezer
for 10-15 minutes...long enough to recover the data before the cds
re-warped...from the heat of the lazer.

A local pal of mine had one STOMPED label come unglued and messed up his CD Writer...

Nowadays CD and DVD blanks are very inexpensive...so BURN EXTRA
copies of those you treasure most.
