CDs, DVDs not so immortal
L33tdawg: I've got LOADS of CDs that have 'rotten' away as well.
Dan Koster was unpacking some of his more than 2,000 CDs after a move when he noticed something strange. Some of the discs, which he always took good care of, wouldn't play properly.
Koster, a Web and graphic designer for Queens University of Charlotte, North Carolina, took one that was skipping pretty badly and held it up to the light.
"I was kind of shocked to see a constellation of pinpricks, little points where the light was coming through the aluminum layer," he says.
His collection was suffering from "CD rot," a gradual deterioration of the data-carrying layer. It's not known for sure how common the blight is, but it's just one of a number of reasons that optical discs, including DVDs, may be a lot less long-lived than first thought.
"We were all told that CDs were well-nigh indestructible when they were introduced in the mid '80s," Koster says. "Companies used that in part to justify the higher price of CDs as well."
