05/06/2004 Archived Entry: "CDs and DVDs Not So Immortal After All"
Posted by CKL @ 10:13 AM PST
From the Associated Press, via Yahoo! News:
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...Hmm... laser rot, anyone? At least with analog you can get some data. Go digital, and it's all or nothing. Not that I'd ditch DVDs to go back to LD, but let's be honest about the tradeoffs.
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...
The aluminum layer that reflects the light of the player's laser is separated from the CD label by a thin layer of lacquer. If the manufacturer applied the lacquer improperly, air can penetrate to oxidize the aluminum, eating it up much like iron rusts in air.

Chocolate Nazis and fashion tips for the season
puhh, well, I hurried and here I am, begging to get a G-Mail account! Why? Because I wanted to dress up and drink coffee with a bisexual friend of mine in the shabbiest place on earth called the rendez-vous. That's why. I just donít have a life, I'd like one, so if you don't have any invitations left, just send a life. I won't send you paypal, because I don't know what that is, if you accept international credit cards there might be a way (but there is none, still). You have none left? Well, listen anyway, Iím just bored. One month and a half left, then I'll be back in Germany. I'm an exchange student (here, USA), just so you know. Frankly, I don't even know you, but guess what, I'll beg anyway, because it's such a humane thing to do. Am I humane? Certainly not, I keep bothering people about things they probably donít even care about. People then always come up with those stupid associations, like that I were a communist spy. And whatís in for me? Well, a mail address like firstname.lastname@example.org, just to please the people that hate me anyway. Itís sad if you actually think about it, so please donít. Just concentrate. What are you doing next? Where do you want to go today (uhh copyright problems!)? Maybe you should eat something, just because eating is awesome. Trust me, I know, and I already look like a wise man. No, just kidding, Iím not too fat, I guess. Donít ask my thighs, theyíll lie. Thatís what thighs usually do, they also complain (wait till they here about the chicken I had earlier!). What was I saying? I donít really know. Do I care? Certainly. Definitely maybe, I guess. Have you ever wondered, if anybody would survive a nuclear holocaust? Okay, it wouldnít be called holocaust, if people would survive. But what would be there? Cockroaches I guess, and probably Cher. Uhh and another thing. Since when do girls know, that guys have urinals in there bathrooms? When do they find out, how? But more troublesome, what do girls have, we donít know about?
Bye. Marcus von Gruenberg-Schmidt (a name Iím destined to have, later, I guess)
