When I was the recorded sound librarian at the University of Texas...beginning in 1982...I started buying CDs for the collection. Our head of cataloging, in her infinite stupidity, insisted that we put labels on the discs. While I am not informed as to the current state of manufacture, back then, as I had predicted, the labels started peeling and took the reflective surface with them.
While on the subject, what is the current thinking relative to printing on CDRs?

I've just tracked a problem here to this very issue on new, white top CDs. After replacing the internal burner. My lot of 50 were dished sufficiently to cause it to exhibit exactly the characteristics Bryan describes. Cost me about 6 hours of studio time and a refill on my jellyfish brain medication order.
Mine played ok on a VLSC player but drove my car stereo bonkers. So solving the problem caused by a warped CD seems to depend on finding a player where it sufficiently adjusts the laser's depth of field.

My experience with paper labels is that the adhesive dries out/shrinks and causes the disc to bow slightly. This can either throw it out of balance, and hence not play at all, or cause it to become unreadable as the laser tracks toward the edge and the distance between the laser and the disc increases. You might have better luck peeling the label off a DVD, or even using some kind of solvent, since both sides of the disc have a polycarbonate layer. That would be a last resort, though.

Subject: [ARSCLIST] DVD rescue
Has anyone had success rescuing video content from a recordable dvd with a label on it? A client brought in a series of dvds of interviews done about
15 years ago on dvd. Apparently the labels have corrupted the data somehow and none of my players or computers can rip or play a complete interview.
Some will play the first few minutes, some even half an hour but errors do set in. Any ideas or tricks hardware software options we can explore?
Content is irreplaceable and most important.
