CD Lifetime?


Just saw this press release regarding 24K gold CDs for archival purposes with a lifetime of 300 years, with the implication that a "normal" CDR has a lifetime of only 6 years.

Any idea what the lifespan of a commercial CD is? Since many of mine are closing in on 25 years old, starts having some relevance... Maybe another argument for burning them all to hard drive, although I've still be viewing my collection as a "backup-backup." Anyone notice any aging effects on their collections?

Remember a cdr is different than a commercially made audio cd. On a cdr you are simply creating a pattern by burning a dye layer built into a cdr. Commercial cd's actually have pits in the surface. Yes cdr's have a short lifetime and personally I think 6 years is pushing it. Commercial cd's are something altogether different and I dont see how the pits in the disc are going away with time.
