Quite. They're bad for two reasons. First, the glue may react 
chemically with the label side of the disc, and damage the reflector 
layer. Second, it may create balance problems when the disc is read at 
high speed.

That's what they claim. But, again, the components in the ink may react 
with the label surface of the disc. If five years from now you discover 
you can't read the CD to which you backed up your data because the 
permanent marker ink reacted with the disc surface, is Sharpie going to 
reimburse you?

Personally, I recommend soft point, non-permanent (water-soluble) 
markers -- if you need to write anything on the CD itself.
