is it safe to apply labels on CD-Rs? The cd-r packages always say do not use labels. Would applying labels cause damage?

Really it depends on who you ask.

The vulnerable side of a CDR is not the bottom -- that's just a thick layer of plastic -- but the top, which contains the recording layer covered by a thin reflective surface. If the label adhesive has a chemical reaction with this surface it will destroy the dye layer underneath and ruin the recording.

Some label manufacturers (i.e., Neato) say that their products are perfectly safe, and could actually extend the lifetime of the disc by helping to protect the recording layer. Some disc manufacturers (i.e., Sony) say that you should not cover their discs with labels whether they are safe to use or not.

For me, the best solution is to use reinforced CDs, such as the TDK HardHat (CD-R74PT). They are designed for thermal printing and have a thick protective coating over the recording layer. The finish is smooth and matte, so it looks good with both transparent and glossy labels, and the protective coating reduces the risk of a chemical reaction between the label adhesive and the recording layer.

Hope this helps.
