First time I've ever heard of it. I've seen it before with discs left in direct sunlight for ages (a year+) but I always thought it was the UV/heat that did it.

About the only disc rot I have ever seen is from cheap ass CD-Rs from back in the late 90s early 2000s. They literally had holes in them after a few years..

I've noticed it's somewhat common with Saturn discs and even some Dreamcast games, they just naturally start developing pinprick-sized holes in them.

If I'm not mistaken, it's unrelated to use.

I thought it was mostly a problem on some cheaper made Laserdiscs...  That I have seen but I've yet to see a game cd with the problem.

My copy of Legend of Xanadu has a pinprick hole in it. Fortunately, it's in a spot that doesn't have any data on it, but I'm still worried about decay. The disc is otherwise in very nice condition.

never heard of it , but i have seen some cheap CDr display it.

It's not something I'm particularly concerned about, as I've not noticed any deterioration on any of the hundreds of discs I own.

Same here. I've never seen it with my own eyes, but I have seen pictures. For pre-Dreamcast games, if it were to rot, it probably would have by now, so just hold it up to the light and see if there any pinholes.

I've seen pinholes on Saturn and SegaCD discs frequently, but copies of the same games I've had since release don't exhibit any holes.  I'm pretty sure that 99.999999% of all holes that appear on those games are due to mistreatment in some way, like people putting the label surface down on something a bit rough. 

The screening on the top of SegaCD and Saturn games is suuuuper thin, making it easy to scratch the top data later part and have holes appear.  I think if the pinhole issue was a widespread manufacturing issue there would be a lot more dead games out there.

Here is a question. Say there is a uber rare game for the Sega cd or Saturn you wanted. And you find it complete but the cd is dead.

Would you still buy it?  Say ithe price is half its typical going rate.

Say there is a very rare game for the Sega CD or Saturn you wanted. You find it complete, but the CD has been replaced with a McDonald's wrapper. Would you still buy it?

Who buys dead (as in completely unable to be fixed) games?

NecroPhile

I'd buy an unplayable copy of something like Dynastic Hero if it was cheap enough (much more than half off), as then I'd actually own the game and wouldn't be stealing it when I played the CDR instead.

I've only seen it with CD/DVD-Rs. Pressed discs are still fine.

Literally ALL of my CDs/DVDs/armpits are rotting.

Similarly how people may buy a import game that is non playable due to language barriers but they feel peace of mind when they play a rom of said game.

If the CDs were made out of metal there would be no disk roat. Maybe disk rust. Lol.

I haven't yet found any games with disc rot, but I have a few audio CDs from the late 80s and early 90s that developed pinprick sized holes in them.  The conventional wisdom when CDs came out was they will supposedly last 100 years but that is untrue - unless they are burned to archival discs and kept away from all the elements, they will eventually fail.  I have a pretty huge optical disc collection (both music and games) and I worry more about them failing than bit rot on cartridges (which, also, will eventually fail).

Edit:  What's kind of sad is that vinyl is actually the best medium for long term storage.  If kept out of the elements in a climate controlled environment, a record will last indefinitely.  Source is this NY Times article (maybe posted by someone here?) about a Brazilian man who is buying up just about every vinyl record in the world!

I have a disc that might be considered disc rot and it just so happens its a PC Engine game.  Received it from Japan in a lot a few years ago.  Looks like something ate away at the top area.  This is the only disc that I've come across. It doesn't seemed to have spread or gotten any worse since I had it.

Possibly.
The odds of me needing another SegaCD or Saturn game is unlikely though; however, like NecroPhile said I can always put a CDR in there, or keep the case around until I come across a loose disc for a cheap price. 

That PCE CD above looks like it was mistreated in some way, like water damage or something.  I've got a copy of Sega Rally with similar marks on it too.

That's definitely water damage. I have seen cd-rs exhibit that when submerged or something get spilled on it. But really, you could (as other have stated) just burn the damn game onto cd-r and play it that way if its that big of a issue.

Pin holes happen in manufacturing. Natural pinholes will be very small, not giant nicks or large chunks missing in the disc top layer. You will hardly ever spot legit pinholes without using a small flash light held up to the disc or something. It's a bit more common then people think. Most don't notice them because so many disc have fully painted labels that cover that kind of stuff up, and back in the day not many thought to do a light check on their disc every time they got a new one.

It has been happening in manufacturing since the 80s though. Its part of what error correction in Cd-drives was designed for and you really shouldn't sweat over them unless you have like more then 10 of them on a disc or something (even then the disc will probably run fine). As a by product this is why you will have disc that will work perfectly fine even though they may have thin top scratches. The error correction on compact disc is pretty solid and you kind of have to go out of you way to make a disc totally unreadable in any given section of the disc.

They were expecting it to happen in manufacturing and there is not much in the way that you can 100 percent avoid it. I have bought new sealed Saturn imports, new sealed PC games from the 90s, new music cds that are mostly unpainted, and other disc, PCE and Sega CD, that have had pinholes upon being opened.  If you are the paranoid type though you can use VSO inspector to check the data sections of your disc for errors, and use EAC to error check the audio tracks to make sure your disc are fine.

As far as disc rot goes. That can cause massive discoloration and flaking off of the data layer. It can also sadly happen without any visible signs to dvds. We have had some PS2 and Gamecube games go bad on us due to rot. Godzilla, Smash Bros, Kingdom Hearts and a couple of others have been lost to it. Disc look visibly fine, but refuse to load, and they fail data checks.

I purchased shining force 3 CIB, with a cracked disc, for just under half awhile ago... Then bought disc only for less than half as well.

I have never seen any disc rot. I truly believe its all due to mistreamment of the disc or storing them in a manner that isn't proper (bulk CD folders, for example)
