List your rotten discs here; CD rot, bronzing, oxidation, etc.

It emerged today (September 16, 2016) that copies of The Enid - Live At Loreley are still rotting. The DVD was presented in a simple card sleeve and it was recognised at the time (2012) that the glue used on the card cover was causing the rot. It was thought that unaffected discs wouldn't deteriorate but I now know that is not the case.
This was a manufactured DVD, not a DVD-R but it's not the only disc prone to rot. So, if you have a rotter please add it here and these releases can be added to a funky list of versions to be wary of.
Note: I do mean disc rot and not just a disc that has been handled so badly it looks like a skating rink.

PS a personal comment about the release, like some found in this thread, will help to inform customers considering buying these releases.

Is this exclusive to glue-caused rot or general deterioration caused by the packaging materials? If it's the latter, then I've got a few with issues from a PVC outersleeve:
MC5 / Afrika Bambaataa - Kick Out The Jams (deteriorates disc in some instances, in most it messes up the color, however,this is probably universal for many picture disc-type releases issued in a PVC sleeves)

The early Reactivate CD compilations are known to have this issue.

For example: Reactivate Volume #1 (The Belgian Techno Anthems)

Excellent point. I recall Madonna's album with the patchouli oil impregnated cover - the oil attacked and rotted the vinyl.

On reflection, I'll add these in the short term but I may move such releases to a Cruddy Packaging list along with Rush - Rush In Rio .
PS I expect to be adding most of the "clear" picture discs from the UK.

The early Reactivate CD compilations are known to have this issue.

Would you be willing to write a brief comment explaining the problem? e.g. "disc rot likely to be caused by..."
PS I note that nostalgia_freak has commented in a Review that the disc is prone to bronzing. Bronzing does not necessarily compromise the disc but I guess that it can go too far.

Bronzed by PDO, UK of course:

Catherine Wheel - Show Me Mary

Just received my copy today in the mail. The cd itself is in mint condition but there are clearly sign of rotting on the edges. I've managed to make myself a 1:1 copy.

How have I not seen this thread before? Very helpful! Thanks!
And thanks Clogwhistle for the list~!

Pretty much the entire Table Of The Elements are in PVC sleeves which will eventually react with the vinyl. Also the sleeves are prone to becoming brittle and cracking...

And the same goes for the entire B 13 label.

The worst case I've even seen is my Soft Cell disc that I've immortalised here:

It's literally just a plastic disc with a film of corroded metal barely hanging on....

Just checked my copy, which is the regular retail edition. Made in , so no PDO rot here :-D . Sadly, I do have some PDO UK discs that have rotted, such as a couple of Deep Heat compilations.

Geez, your CD looks like it took an acid bath or someone put it in the microwave :-o .

For those in doubt:

Look at this on eBay http://www.ebay.com/itm/252763342408

i ed images of disc rot present on the discs to Hole (2) - Miss World.
oh and look at that, PDO UK strikes again.

i feel like Clogwhistle's list will be made up entirely of PDO CDs and coloured or picture-disc records housed in PVC sleeves.

I feel like Clogwhistle's list will be made up entirely of PDO CDs and coloured or picture-disc records housed in PVC sleeves.

s of the LaserDisc DataBase will know that PDO UK, Blackburn, is not the only pressing plant that produced rotters. According to this https://www.lddb.com/laserrot.php PDO UK is 4th in the table of manufacturers; but this of course relates to LaserDiscs. DADC USA is the number one on the list.

I think that if you're ing images of damaged discs you should place them in Disabled Images and add a link to the image in this thread. This image https://img.discogs.sie.com/BeVeJDoqI_bkeoEYc-xkTq2N9a4=/fit-in/600x600/filters:strip_icc():format(jpeg):mode_rgb():quality(90)/discogs-images/R-4571439-1369238424-2160.jpeg.jpg is currently the main image. Hopefully one day it will be replaced with an image of an unaffected disc.

The thing to bear in mind is that this is the start of a list of Buyer Beware releases. Though an entire release might be affected by rot, it is also possible that part of the pressing run has not been affected. I had a bronzed CD by Ozric Tentacles (I think it was Strangeitude) but I have since replaced it with a non-bronzed copy.

the images are added as addendum and can aid interested buyers and show the matrices, so i see no issue with them being on display vs. disabling them.

thankfully the two i gave as examples are cd singles, so in the case of the Hole CD, with the disc rot creeping slowly from the outer edge-in, there is a lot of space between the last audio track and the disc-rot. i may get another decade or two out of it.

All About Eve - Winter Words - Hits And Rareties

bought this one (used) a couple of days ago and the disc surface is completely bronzed. Thankfully even in this case i've managed to make myself a 1:1 copy. Another brilliant PDO pressing.

Side note, for those not aware:
If people are trying to rip rotted discs accurately, for Windows, there's CueTools, that may help in repairing bad rips. They maintain their own database with checksums (sort of like AccurateRip), and depending on how bad your rip is, CueTools might be able to repair it. Freeware.

Art Of Noise* - Daft - PDO, UK - initially listed as a Gold disc variant, it's just bad bronze rot. It is not clear if the seller with a €39.99 copy listed has missed the fancy gold => dodgy bronzed update or simply trying to make "rare! vintage PDO rot!" a collectible thing.

P.T. Barnum would have been proud.

I had to chuck out my Complete Columbo DVD collection as half of the DVDs were sticky and unplayable, and I think at least some of the other discs were on the way out.

Another PDO here brown /yellowing edges of my CD
Jello Biafra With Nomeansno - The Sky Is Falling And I Want My Mommy

I have a few CD's, mainly singles, that have developed a kind of cloudy blotchy appearance on the data side. All are in Digipak(R) which I suppose is the culprit. Another factor might be that I've kept the CD's untouched in the sleeves, in the shelf for years at a time and I've also stored them in protective outer sleeves. I am guessing some kind of gas buildup has accumulated inside which has then attacked the discs. The 'rot' has stopped from advancing after I've separated the discs from the trays.

Shara Nelson - Nobody

I have CD's from around the world and from all eras since the 80s, so it can't be a coincidence that all are from UK and are 'Glass Mastered At – EMI Swindon'.

I'm not sure whether these should be added to the list yet. You say these are all in Digipaks? I think I'll check my Digipak discs and see if I have a match for the effect you describe. Certain glues in the packaging and / or the disc itself appear to be the culprits for disc rot so I guess this might be worth looking into.

1999 release, bought new and sealed in 2018. Disc rot quite evident upon opening, and am waiting seller to ship a replacement. We'll see what that one is like whenever it arrives. Never had a problem with other CDs from this label Golden Years Of New Jazz

Replacement had the same issue, so it looks like a problem from manufacture. I've not had any other problems with that label.

So you have it as well? Sorry. That wasn't clear to me when I read your post. Re-reading it you did actually make that clear. I will add it as your nomination.

Looks like the sort of rot normally reserved for mid '80s releases but this one is from 1990. It has holes in the silver that you can now see through. Still plays all but one track:
Gentle Giant - Free Hand

One of my very first CD purchases 35+ years ago, classic laser rot:
Mike Oldfield - Tubular Bells

Edit: Add this one, a very early CDI pressing. It looks fine but it skips on one track and cleaning won't change that. It's on Yehudith Ravitz* - דרך המשי = Silk Road

To be fair most of my original 1983 through 1985 CDs are still fine. Last night I listened to a 1987 CD made in Austria for both the Israeli and European markets back before Israel had any CD pressing plants. (Manufacturing in Israel by CDI Ltd. started in late 1987.) It still looks like a new CD other than a couple of very minor scratches and plays perfectly. It was among the first CDs made for the Israeli market on CBS and it has held up remarkably well.

ooops, I hit wrong thread (bloody iPad) sorry

Fauni-Gena
Still plays all but one track:
Gentle Giant - Free Hand

Would the one track it doesn't play be the last track; Mobile? Do you have Nero software on your system? There is a feature called ScanDisc that I use for indications and confirmation of disc rot / physical damage to CDs. I would be interested to see what it makes of your disc.
Apparently, holes in the reflective layer are normally the result of the manufacturer using insufficient metal to produce a complete reflective layer. Those holes have always been there, or so I understood. Or do they increase in size?
Yours is the second (or third) Canadian disc I've noted today as a potential rotter. Perhaps there was a problem with a Canadian pressing plant?

Clogwhistle
Perhaps there was a problem with a Canadian pressing plant?

I wish I'd kept the Canadian New Order disc, but it was my first "rotter", was very frustrating, and I tossed it. The label side had solid printing so it might have been hard to tell if it was classic bronzing anyway. I have heard the reports of cardboard sleeves being trouble under some circumstances, which was this disc's original packaging, so that would be my first guess as to what went wrong. I don't have a ton of Disque Americ releases, but the rest are fine.

Fauni-Gena
To be fair most of my original 1983 through 1985 CDs are still fine.

I find the same thing. The discs I listed above are all the rotters I've got out of a 1700+ CD collection. Only other was an old pre-TVT Wax Trax! copy of Ministry - Twelve Inch Singles (1981-1984) that I tossed once I found a working copy, so unfortunately I couldn't authoritatively say which pressing was rotten.

Clogwhistle
Would the one track it doesn't play be the last track; Mobile?

Yes.

Clogwhistle
Do you have Nero software on your system?

No. That's a Windows app. I run Linux exclusively since it's what I do for a living in large part.

I just looked at the disc again and the black ink of the label's logo is now bleeding through to the playing side of the CD as well. I'm trying to play it now and I'll update this.

Clogwhistle
Yours is the second (or third) Canadian disc I've noted today as a potential rotter. Perhaps there was a problem with a Canadian pressing plant?

I don't know. This one was made by Disque Americ. I have a bunch of CDs manufactured by them but this is the only one that skips and looks like crap. The idea that it could be insufficient metal makes sense given that I can now see some of the logo ink on the playable side. It's probably been that way for a long time and I just didn't pay much attention to it once I knew the disc had an issue.

Update: I played it again. Same result: it skips on Mobile, all other tracks play properly.

Note to self: Buy a new copy of Free Hand already.

35DP

Thanks for the reminder. I replaced my copy of CBS. I do have a bunch of Israeli pressings from that era and most are just fine. The fact that two from the same plant from one of their very early production runs may be coincidence or it may be an example of a real problem. I honestly don't know.

Another PDO pressing with bronzing issues:
Alien Sex Fiend - Acid Bath

35DP
I have heard the reports of cardboard sleeves being trouble under some circumstances

This was the issue for the Enid release that triggered the Rotters list. The whole issue of rotting seems to be linked to the make up of particular glues used, either in the disc manufacture or in the covers.

Apparently, holes in the reflective layer are normally the result of the manufacturer using insufficient metal to produce a complete reflective layer.

One article I once read said that holes appearing in the silver layer are the result of dust particles due insufficient clean air filtering at the manufacturing plant. Ideally CDs should be made in a totally sterile environment. Thus, if dust gets into the metal layer it breaks down and reacts which can either cause holes, greying or bronzing. Greying was typical of many early Italian releases pressed in Austria. A theory on bronzing is that the metal layer included ferric elements which rusted.

Makes perfect sense.

Does this mean the damage is progressive? As far as I can tell none of the holes on my discs are the same size as they ever were.

If it is caused by contamination within the disc, then yes.

As I run across bad discs in my collection, I put them in a list:
https://www.discogs.sie.com/lists/bronzing-disc-rot-failing-CDs-etc-my-collection-only/435081

One disc made by BOD and several made by Discovery Systems became unreadable over time but still look perfect.

Several of the discs made by Nimbus UK and PDO look bad (bronzing, edges deteriorating, pinholes) but most of them are still readable.

I thought the PDO problem was UK only, and indeed that's the plant that seems to have produced the majority of bronzing discs, but I have bad discs made at the US and German plants too!

In fairness, the majority of my discs from all of these plants are not rotting, as far as I know.

Clogwhistle

No physical damage. The marks that look like crackles just appeared there on their own. They and the cloudy areas were there when I noticed the damage. I bought the CD new when it was released.

Pheenixx
Was that The Final Rip Off? Mine was exactly the same.

Yep. That one was by far the worst of my PDO UK discs.

Also this Swindon disc has a cloudy spot in my copy:
Kate Bush - This Woman's Work

Another EMI Swindon disc, almost throughout cloudy:
Shara Nelson - What Silence Knows

As I just received another CD with disc rot that was made by White Christmas And Other Holiday Favorites appeared to be completely transparent when held up to a light. Normally, I've found CDs to be more reflective, so I think this disc was somehow completely rotted through. It surprisingly ripped in burst mode but had audible glitches, so I'm not sure what's going on there, but I sent it back and have another copy on the way.

Out of over 1,500 other CDs that I have, these are the only ones that I have ever purchased that have had major disc rot where they cannot be ripped accurately.

Tears For Fears - The Seeds Of Love, released in 1989. Still played fine, the last time I checked (about a year and a half ago), but in some places I can literally see through the disc. As far as I know, this is the only disc in my 10,000+ collection to have visible disc rot.

I don't have a ton of Disque Americ releases, but the rest are fine.

Disque Americ is the problem. From inception to the early 90s, some of their discs suffer from rot. I'm guessing that they had a problem with one/some of their machines. You can't tell which one is rotten, though.

I've got two copies of New Order - Substance that are rotted.

I've had three copies of Moev - Head Down that wouldn't rip securely/accurately, then bought a US pressing so I wouldn't keep wasting money buying the CA pressing in hopes of getting a good one :-D . I think all of my Nettwerk CDs that were made by Disque Americ cannot be ripped accurately. No problems with the earlier Praxis/Cinram pressings, though.

Fortunately, most of my DA rotted discs still play okay, but I do have Tom Cochrane & Red Rider - The Symphony Sessions, which is so rotten that it sounds like static.

The latest Duran Duran - Duran Duran, released 1993.

Thankfully, Capitol and PolyGram eventually switched to Cinram, and I've never had a problem with Cinram CDs.

Coil - Stolen And Contaminated Songs (got replaced pretty soon but with a different disc design)

obs
Disque Americ is the problem.

Interesting, and I would not be surprised to find that the Ministry disc I mentioned was manufactured by them too - Wax Trax! sent a lot of their pressings to Canada.

Did pick up another copy of that Round & Round single on the cheap and crossed my fingers until it arrived - Disque Americ, plays fine. Odd.

But I’m wondering about my old Skinny Puppy discs now, which I ittedly haven’t played for a while... hmm.

35DP
But I’m wondering about my old Skinny Puppy discs now, which I ittedly haven’t played for a while... hmm.

My copy of "Mind:TPI" doesn't rip properly, nor Tear Garden, "Tired Eyes...". While I didn't switch to CDs until the late 90s, I did grab "Bites and Remission" when it came out, so I have the Praxis pressing. I also have a Disque Americ pressing, and it can't be ripped without errors.

I recommend ripping those old DA discs now because you never know. Playing fine isn't an indication that the CD is fine, since CD players are quite forgiving, whereas secure CD ripping doesn't gloss over read errors.

All pressed by Faith No More - I'm Easy / Be Aggressive

Signs of bronzing on the disc face. Playable surface has, however, no signs. I'm Easy / Be Aggressive made some loud clicks when the CD was inserted into the player but it played fine after that. Repeated the process a couple of times and it stopped doing the loud clicks.
Ripped fine as well.
But the future is not so bright for this one, I'm afraid! :(

Tragicomedia With Michael Chance, David Cordier - A Musicall Dreame
I've had two copies of this Hyperion release (made in UK by PDO) with bad bronzing; first had tapping sound throughout later (outer) tracks, second (currently) still plays OK.

De La Soul - 3 Feet High And Rising - PDO UK in jewel case. Bronzing. Still plays but struggles with ripping on the last few tracks where the bronzing is at its worst.

Fairly sure I'll find more affected discs next time I check my collection.

Found 3 more older Hyperion discs with light bronzing to label side, all made by PDO in the UK, and notionally dated 1988 to 1990; all three still play OK:
Robert Fayrfax - The Sixteen, Harry Christophers - Missa Albanus & Aeternae Laudis Lilium
I also have a heavily bronzed copy (on the label side) of a disk already in your list, also made by PDO in the UK, but still playing OK at present:
Misty In Roots - Live At The Counter Eurovision
As this latter would probably feature in my Top 10 of all time, it is particularly galling given that it has still not been since reissued on CD, a remarkable situation.

With the one previously advised, that's a total of 5 that I currently know of in a collection of over 6,000, so I guess it could be worse...

Bronzing on my copy of The Rolling Stones - Hot Rocks 1964-1971

affects both discs but only one spot where it has degraded enough to cause playback issues on 1 or 2 tracks

Full-on rotter. Utterly useless.

Underworld - Spikee / Dogman Go Woof

Being gold laminated doesn't seem to have saved this one. Not visible rotting but on its way out.

Julian Cope - Jehovahkill
