Anyone remember this scare back in the 90's?

supposed indestructible CD's were being hit with strange rot / markings on the media layer which was rendering discs unusable.

I was going through my cd collection last night, looking for some tracks to rip, when i noticed a strange mottled effect on one of my cd's


on closer inspection the printed surface is intact, but looking from the side that is read by the laser, i have a load of little blemishes in the substrate, but the disc is not scratched or marked.


i haven't tried to play it but suspect it will be fubarred.

any ideas where i stand in getting a replacement? I'm guessing its a now deleted item

Im having the same problem with some of my DVD's. They've started to skip.

got several cds that have the same problem-funnily enough only on pressed discs not cdrs. Some still readable on a decent pc cdrom tho for some reason.

I had some a while back that went like that - I think they were all Polygram disks. I wrote a letter complaining, pointing out that they didn't offer the lifetime of listening pleasure promised on the CD packaging. They asked me to send back the faulty disks and they replaced them.

Removed.

The best at resisting the rot are re-writeable disks. I've had cd's since the 80's and the biggest killer is mishandling. I don't think I've ever had one die due to old age

Accelerated testing in labs has shown it to still be a problem in extreme circumstances. The usual advice is if you want to archive to optical disk, use good quality disks, and redo them every year or so.

Got a couple of not very old writable cds iv put music on with similar markings - looks like severe mildew/leaf rot in places,

dont seem to affect performance
