If you are asking how long a CD-ROM will last if treated properly, I don;t think anybody knows for sure. CDs are burned with a serious of little dimples on the surface of this disk, that are translated by software into binary. Theoretically if the disk is kept dust and scratch free (and out of the sunlight if you are really paranoid), the only danger should be the eventual chemical degradation of the material used to manuafacture the disk, which should take an awfully long time.

You are in greater danger of the CD-ROM format going obsolete than the disk degrading.

Maybe one of the scientifc guys on the forum can add something to this pretty non-scientific answer.

There is a scientific paper published by Kodak at:

Why did Kodak stop manufacturing CD-R discs? They found out that their "Lifetime" warranty was in jeopardy with these discs. I do not believe there is any problem with future compatibility. You can still buy Zip drives and floppy discs and drives. You can get turntables for LP records. The CDs will read in DVD players and ultimately everything comes to an end. CDs are vulnerable to a host of things and the worst is the side of the label. The data is underneathit at that side. The gold coating Kodak used was on that side to prevent environmental damage. The writing of the pits on the recordable surface it suspect. The CD readers use a high intensity laser and I believe they are not very well regulated in that they vary in frequency and color. It can ruin a CD-R if played a few times. This is not supposed to happen but it is enough to stop relying with a "Lifetime warranty" on the writable CD. Kodak did just that.

Some people posted helpful links ...

what I remember is that CD's last 100+ years CD-R's 10-50 years. This is less than the other posts state.

It is a good idea to burn important data on two CD's and reburn it every 10 years, which may be necessary anyways if the CD media bcomes obsolete.

Important to know is that CDR's are a lot more sensitive to age, physical damage and environmental condiditons as are pressed CD's!
