Fred Langa has had several articles on preserving CDR disks and what
causes them to deteriorate. Your particular question can be answerd
with this article by him. There are references within for additional
information on how and why cds go bad.

So what actually happens when the "lifespan" runs out? I still haven't
got into CD burning, but it's a project that I have planned for the very
near future. At least until I read this piece of news.
I have a collection of tapes going back decades, and they are still
playable. Of course our expectations are always rising, so we become
impatient with analog sound or the inconvenience of manipulating tape,
but they sound just as good as they ever did. A very low grade tape
will become brittle or shed its coating. So what happens to the CD's?
And how does anybody know? Has this been written up anywhere?

I have been told that if you burn a copy of a music cd to a blank
CD-R cd, the copy would have a life span of two to five years. If
you
save the copy to the hard drive on your computer, what is the life
span of the copy?
thanks

I remember when they used to say CD's had "an infinite lifespan"
because
they didn't know how long they lasted, then they said 50 years, now
it's
2-5?
