I've been looking at buying a CD label machine. It's the kind where you print them on a home printer. I've noticed on CD's that have these paper labels, with my powerbook, every now and then the CD will hang coming out of the slot drive because the CD is thicker than without the label. It got me wondering if these kinds of labels can possibly be harmful to any part of my disc drive? Does anybody know if it's possible for these labels to harm any part of a computer?
