Don't know about the glue eating the data layer. I thought labels and adhesives just took off the reflective layer causing a loss of readability. Data is still there if you can replace the reflective coating...
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. ;)
I have had numerous problems trying to read old floppy disks. While that was almost the only backup medium, it has turned out to be pretty flaky. Old audio tapes may sound OK, but who knows how many drop-outs there might be in a digital version of same? I would guess that a number of major corporations are finding that their digital tapes are not completely readable--but you'll probably not read that in the Times' business section! It would seem that the perfect backup medium would be carving on stone! --doug -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
