I've found on some cheap media the lacquer on the label side is very
thin, making it easy to chip the reflective layer and lose data.
I've also erased CD-Rs accidentally by leaving them in direct sunlight.
The UV seems to bleach the dye out of the data layer.
Other than that I've had remarkably few problems reading CD-Rs that are
a decade old. CD-RWs seem to suffer more from bit-rot. My 20-year-old
720K floppies aren't doing so hot, either. ;)
