Hi
I have just though of listening to some of my older cd's and I put them on and they skip and jump and just generally sound like , I got rid of my old cd player since I thought it was doing it.
Now after about a year on my new cd player and on my cd rom the cd's are sounding like , it's definatly the cd's not the player since all my other cd's sound just fine.
I take extremely good care of my cd's, i've cleaned them , not one of them have a scratch, but they still do this... could they be worned out? |

| No matter how well you take care of them, CDs have a very finite lifespan. Recordable CDs are even worse. It's not the way you take care of them, they just seem to degrade over time. |

| Cds have a short lifespan, thats why you have to force them to reincarnate. (cd-r) I'd really like to know about how old are the cd's that are doing this? |

I have 8 cds doing this, the oldest one 1997 and the newest one i bought 2002 (2 disk set both are doing it)
All 8 have had some llllooooooooooong sessions of playing though.
5 of them where doin this on my old player, thats why I got rid of it, on the new player they still do it but now 3 more have joined the club, but mind you I have not listened to them for like 2 years.
Strange what one finds when you want to listen to some of the old goodies. :(
none of them work on my cd rom either and thats not even 2 months old. |

I searched a bit for more info on the subject and i got a few things...
Apparantly its claimed that cdrs have a lifespan of approx. 100 years, and cdrws a lifespan of 30...(this is said by hewlette packard)
More realistic studies have shown that the normal silver (aluminum substrate) cds have a lifespan of about 10 years. Although gold substrate cds should last over 100 years, but dont ask me where you buy these gold cds...
As far as cdrs go, ones that used organic dyes have a greenish reading surface. These have a lifespan of 10-30 years. Gold substrate cdrs again last over 100, and again i have no clue where you get them. The newer and more common ones have a bluish tinged reading surface, and studies havnt been done on them, but they should be similar to the ones that used organic green dyes. |

Cool. Does the lazer degrade the cd, or does it break down with age , oxidization and such? I ask since I have some really really old cd's that work perfectly.
I have seen some cdrs that are gold, never any other cds though |

As far as i know not much of the process is due to the laser, i know that sunlight(direct) speeds up the process MUCH faster on cdrs, i wouldnt guess that things such as humidity, and other stuff like that might be a factor?
Heres a thread you might want to check out, (its where ive been getting most of this info.)

I know its in regards to storing images on cds, but its still helpful. |

Thanks man
How do I get my busted ass cds to work again?
I didn't leave them in the sun
They not scratched
They not dusty
been kept prestine
Which brings me to another point.
WHy the hell do people work so thoughlessly with other peoples cds??
I once got a cd back from this one guy, he lost my jewel case, the thing was scratched to hell , and it even had a crack in it. And the best part of it, he dropped it off at my house when I wasn't there, never apologized or anything, then I phone him, and suddenly there was nothing wrong with it when he dropped it off... What the hell is wrong with people?
I have had people steel my cds also
And now the things just stop working all together...
I remember when things came on tapes... those where the days :rolleyes: |

| Oh god i hate tapes. I've owned 3 tapes in my life, the first i got when i was 6, and i loved it, i carefully stored it in its case in my drawer. Well one day i go to listen to it and its all screwed up, and my dad says its been erased...how? I had a magnet in the same drawer that i stored the tape in...stupid? yes, but i was 6 and they never taught us that magnets erased tapes in public school. |

hehe
The other crap with tapes is as soon as your tapedeck has had enough it politely tells you buy chewing up your best tape. When you take out your tape and it makes that wooooooooooor sound you know you gonna have to sit there for an hour to reel all that back in :D |

| cool little fact of the day. i read an article in Computer music that said if you allow sun light to hit hte back of your CD-R's they will last longer. I guess they were doing a study at stanford(and still are) and they proved that sunlight helped the reflective capabilties of the CD-R, which insures longer life. |
