Where is the Beef? It would be nice to have some stats, test results, etc...
Although opinions vary on how to preserve data on digital storage media, such as optical CDs and DVDs, Kurt Gerecke, a physicist and storage expert at IBM Deutschland GmbH, takes this view: If you want to avoid having to burn new CDs every few years, use magnetic tapes to store all your pictures, videos and songs for a lifetime.
But from the land of big glasses and smart dudes we get some
different info...
NIST has found that recordable disks seem to last much longer than rewritable disks, Byers said, and even longer than manufactured disks such as CDs for installing commercial software.
General industry guidelines now estimate office-burned copies of CDs and DVDs could remain readable for 100 to 200 years.

This has been reported for years. Generally, discs (RW or R) have been found to deteriorate, and quite easily. The problem is perception: Disc storage has been promoted as the "permanent" (or at least long-lasting) data storage solution, so it's likely that people are socking away discs that they won't look at for several years, by which point it'll be too late to recover. Especially worrisome for official records in government and business.
