Hi Frank:

Are the sleeves PVC on both sides or a cloth type on one side and the 
PVC on the other (only the top of the disk faces/stuck to the PVC) like 
an album binder that stores multiple CD's on the same page?

Have you tried a simple hair dryer to GENTLY warm the PVC. Then while 
keeping the sleeve warm, GENTLY peeling the PVC from the disk? If the 
sleeves are multi pocket, cut out each pocket from the sleeve so you can 
work on them individually.

This has worked for me, although the sleeves were lightly stuck to the 
disks, more bonding time may have made this something I might not have 
been able to do.

Hot water might be another alternative.

If the PVC is stuck to the bottom data side of the disk, you might have 
bigger issues. Obviously damaging this side will effect playback and 
might require resurfacing. We have an RTI disk resurfacing machine here 
that does a great job. Would highly recommend them.

If this does not work, my next step might be to use one disk as a test. 
Keep the PVC on the disk and trim as neatly as you can, the PVC from the 
outside edge of the disk as well as the inside hole of the disk. There 
is a chance the disk still might play so that you can pull the 
information off it. I have not tried this myself, just an idea. The key 
is to trim as carefully as you can. A disk that is off balance will not 
play and can damage your disk, your disk drive or both severely.

This is also a great reason why not to use the paper sleeves with the 
thin clear plastic window on the front. I have seen a huge collection of 
disks stored in sleeves with the clear plastic window also stuck to the 
disk although I didn't have to work with that collection.

Kind Regards,

John Schroth

At Stanford we recently received a donation of a large number of CDs, but the original owner put many of the CDs into PVC sleeves to save space.  We are now encountering the problem of the printing on the surface of some of the CDs sticking to the plastic sleeves, so that removing the CDs from the sleeve may damage the CD by removing the lacquer and exposing the underlying aluminum.   Has anyone dealt with this issue and come up with a reliable process of removing the CDs safely from the sticky PVC sleeves?
