CDs you own that have degraded over time? (CD rot)*

Hi folks I have recently started collecting classic CDs should I be concerned about Disc rot all the cds in my case are in Mint state in terms of media and all japan for japan Sony discs

 

Disc rot affects CDs made in the UK at the Phillips & DuPont Optical plant almost exclusively. Your Japanese releases should never be affected.

 

I have some original CD's that I bought in the 80's...they've yet to rot on me and play as well as ever. Your Cd lazer will rot before the discs ever do.

 

I hope thats true
Just in case Thriller 35 8p 11 111A3
BAD 32 8p 200 First Press
Dangerous ESCA 5500
?

 

I've only had two or three that have oxidized per one thousand, so the ratio is still excellent.

 

If it looks like this you're in big trouble.

 

so would this be affected ?

 

am i bring paranoid ? the cost to go get the discs keeps flashing in my head when i think about it knowing i may open the cabnet to find them in a bad way like above

 

'Resonated' is right. This problem was limited to discs manufactured at the PDO (Philips DuPont Optical) plant in the UK, all prior to 1990, and fixed thereafter. Anything from Japan should be just fine. So, no worries!

 

My PDOs are bronzing slightly but still playing fine

 

If you worry about it too much and die from that worry, it really won't matter now, will it? So chill and know there are many more important things in life to worry about.

 

Try sending it back for replacement...

 

This problem still existed after 1990. My newest bronzed CD is from 1992.

 

i have a metallica cd single that I think appears to be rotting

 

The worst one is the Chiffons compilation on ACE. Completely destroyed by rot.

 

Have you contacted them? I did for my Dyke and The Blazers comp made by UK PDO.
Another bad one is my copy of the 'Girls, Girls, Girls' 2-cd comp by Elvis Costello.
UK PDO too.

 

All my CDs play perfectly. The oldest one is 32 years old.

 

I've got Girls Girls Girls and there's no rot. Must be a later pressing. The Shag Times CD is worth a lot and every one I've seen is rotten to the core.

 

If in doubt, try to rip the CD using ripping software that uses AccurateRip. If you keep a lossless AccurateRip verified copy, backed up, you then have the option of burning a replacement CD-R if the original fails. I think I have had maybe 1-3 rot out of 1100. I have had far more DVD Video failures.

 

I have the fatboy version with the completely dried up foam inserts!

 

My copy of Layla has those dried up pieces of foam.

 

My two Sony SACD-players don't recognize the SACD-track of "Rumours" and "Nightclub" (Patricia Barber MoFi-SACD) anymore.
The cd-track is playing well but that's not what I bought these discs for.

 

Same here. My oldest CDs date back to 1984, and none of them exhibit any rot. I have CD-Rs that I recorded going back to the late 1990s, and they all still play fine. Those don't even show any discoloration.

I know there were some defective pressings that now exhibit rot, but I've yet to see one in person.

 

I don't think that is disc rot, even though I'd be curious to know what caused it to fail.

it's possibly still affecting that external part of the disc that doesn't have data in it

yes, you are.
Japanese CDs from the eighties don't rot.
Some have found some whitish substance on them though, like crystallization or something. But only on sealed one, as far as I know.
