I don't know man. I've only ever had 1 CD ever get it.

Maybe in another 10 or 20 years shit might start dieing. But from the 1 CD I have with it, it happened only a short while after I got it.

Here's my pic again. I haven't seen anyone else post evidence of it. So I assume it's pretty rare. But it definitely happens.

If they do need to be cleaned I use a micro fiber cloth and 99% ipa.

The one plus of that Saturn CD is the system continually tries to read it so it makes for a good test CD.

I've only ever heard of it happening to anything pre-PS1 (Saturn, SCD, PCECD, Laserdiscs, etc), and some music CDs pressed around/before that timeframe. I have some SCD games that are rotted, my copy of Silpheed actually won't play past the first level because of it. However, in my experience, anything that will rot has already started. Everything pressed in this time frame isn't susceptible, I believe, only certain batches of discs.

I also need to add I have never seen an example of a PS1 game rotting, or anything after that (though anything after is somewhat new in comparison).

If it hasn't been mentioned already, the 'rot' is oxidation of the data layer of the disc. Bad pressings caused minute amounts of oxygen to get trapped inside the disc, causing the data layer to, very slowly, get eaten away at over time. It might not effect some older games even if they have rot because many of them don't use even close to the amount of data available on the disc.

Working at Gamestop I've seen more PS3 Blu Rays with disc rot than I've ever seen of standard discs. I don't know what it is about Blu Rays but it's always the ones that have been treated like shit, like not being kept in their case. Sometimes it's as small as a pinhole, sometimes it's a huge gash you can see right through. It's always dependant on condition, though. Never seen a game kept in good shape with it.

Do you store your discs horizontally or vertically? Does anyone think it matters?

There's the whole thing about the effect gravity could have on the disc when stored horizontally (as the edges are not directly supported) but that seems a little off to me.

So-called disc rot is a real thing, although it has nothing to do with decay and is not the inevitable fate of all optical media. People use "disc rot" incorrectly to describe a variety of faults, usually scratches on the data layer; it's actually due to imperfections in thermal ink used for printing CDs. It almost always appears in the entire run, not just a single disc.

I work for a media duplicator in the NW, and in my six years here I've only heard of it happening once. If CDs are stored correctly, you should not ever experience any problems with them. Keep stuff out of direct sun, severe changes in temp, etc.

Where are you getting that? It's still the same basic format, just the data is packed together tighter than a cd because the laser used to read it is a higher frequency waveform.

due to the higher storage density, a scratch on a BD would damage significantly more data than a CD or DVD

Just popped in to say this whole thread is retarded because all of you are arguing over "disc rot" and it's meaning and if that is or isn't disc rot when it's apparently an undefined term that means "bad thing happening to cd that doesn't have a direct mechanical cause" which is like 50+ different unrelated things with completely different causes. It doesn't help that none of you are attempting to explain what thing exactly you're talking about, just running with "disc rot" as whatever you decided it to be and then arguing with each other why what they're talking about isn't the same as what you decided disc rot was.

So UV damage, chemical reactions other than oxidation, manufacturing error, etc, aren't disc rot? Because I've seen all of those referred to as "disc rot" before.

I had no idea oxidation was UV damage, adhesive delamination and all other chemical reactions!

On a more serious note, are you saying that all disc rot is oxidation because aluminum once exposed to air will oxidize? Cause that's completely disregarding the various failures that lead to the aluminum being exposed in the first place, and a bit like saying all deaths are due to cardiac arrest since when someone dies their heart stops beating.

Even the CDs I burned in the mid 90s still work perfectly.
The only CD I have which is affected is a music CD with a few very small visible holes, but it might have been like that when it was new, I dont know. And an early release of Pink floyd's Dark side of the moon has an almost transparent data layer, but works fine.
