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.

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?
