CD Warp

[yoshi1668]

has anybody had this experience. I put CD label on a set of CDs, about 200 of them. After a little more than 6 months. All these CDs that have labels on them are warped. Curve upward around the edge, that is. These CDs cannot be played anymore in computer but still OK in DVD player. I have another batch of CDs without label within the same time frame and has no problem at all (perfectly flat).

It's possible that when you applied the labels to the CD's it was warmer outside and more humid, and now it is colder and drier (are you in the U.S., or elsewhere in the northern hemisphere?). The label may have shrunk slightly, but the adhesive is holding tight. Therefore, the disc might tend to warp as your describe. This is just a theory, though.

Yes I'm in New York. That means I should never use CD label anymore.

What brand are you using? A good quality brand should not do what you are saying.

[yoshi1668]

I have to say all brands. From Imation, TDK to some no name brand like Hypermedia. However, the labels that I use are all Avery product which is a very strong product.

This is why I use CD pens and nothing else......

I don't suppose that if you removed the labels, you couldn't flatten the discs again? Perhaps if you heated them up in warm water and gently placed a heavy book on top, it would gently put them back into shape without destroying data. Pick a victim......

Get the steam iron out !

No, seriously, have you got a picture ? I'd love to see that. I know I shouldn't gain satisfaction from your misfortune, but I've never seen a disc do that before. I've seen one "sag" in the middle from extreme heat (it was in an environmental chamber and it had "fused" with the jewel case), but I've never seen one bend like that on it's own.

Normally the heat required to do that would kill the player too, so if you're worried about leaving discs in the car, so long as they're in the glove box or a changer in the boot, they should be OK for short periods at least.

It's not something silly like you've got some very tight jewel case inserts that won't let go, and years of pulling the disc by the edges as put a slight bend in it, is it ?
