What is DVD Rot? Can You Fix DVD Rot? [1]
– 2 Composition of Reflective Metal Layers in CDs, DVDs and Blu-rays. – 5 What Causes ‘Damage’ to DVD’s Metal Reflective Layer?
When we talk about DVD rot, we talk about the ‘damaged’ metal reflective layer of a DVD.. All optical discs -CD, DVD and Blu-ray – come with a metal layer.
Without the metal layer, laser from a DVD player will shine through the disc.. When the metal layer degrades or is ‘damaged’ disc rot sets in
Wikipedia [2]
Disc rot is the tendency of CD, DVD, or other optical discs to become unreadable because of physical or chemical deterioration. The causes include oxidation of the reflective layer, physical scuffing and abrasion of disc, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together.
The lacquer protecting the edge of an optical disc can usually be seen without magnification. It is rarely uniformly thick; thickness variations are usually visible
In ordinary use, a surface layer of aluminium oxide is formed quickly when an aluminium surface is exposed to the atmosphere; it serves as passivation for the bulk aluminium with regard to many, but not all, contaminants. CD reflective layers are so thin that this passivation is less effective.[1] In the case of CD-R and CD-RW media, the materials used in the reflecting layer are more complex than a simple aluminium layer, but also can present problems if contaminated

So your CD won’t rip without errors? In order of severity, this is caused by:. The following diagram illustrates the physical structure of a CD:
For conventional pressed CDs, the data isn’t encoded into the layer itself, the data is pressed into the top of the polycabonate layer using a master and is made reflective with the thin coating of aluminum. Without this reflective layer, the data cannot be read.
– Polycarbonate is /very/ tough material – safety glasses are made of this stuff. – There is very little protection for the critical aluminum layer on the label side: just a thin coating of acrylic sealer and the label varnish.

Disc Rot or Laser Rot of CDs or DVDs [7]
Disc rot and laser rot are terms used to describe the degradation of optical discs. It can often be referred to as CD rot and DVD rot as well, depending on the format of optical disc that is affected
This page takes a closer look at what disc rot is actually is all about.. All optical discs contain a metal layer within the disc structure

Avoid Disc Rot: How to Look After Your CDs | Discogs Digs [8]
Disc rot affects CDs, DVDs, Blu-rays, and LaserDiscs in different ways depending on how they’re manufactured and structured.

Hell, I’ll admit, that with the exception of surface abrasions, I thought there was little you could do to corrupt a compact disc. Check out the BBC’s Tomorrow World’s totally convincing demonstration of the marvels of the new CD format:
Great, as if it wasn’t enough that my stylus is wearing out my records, and my tapes are all unspooled – now I have to worry about the degradation of my CDs as well. The answer is dependent on a number of factors, including where the disc was manufactured and how it is stored.

CDs and DVDs can be reliable for many decades with proper handling. As with all other types of media, degradation is inevitable over time, but steps can be taken to help prevent it from occurring prematurely
Optical discs will perform well within a wide range of temperature and relative humidity conditions. Discs kept in a cooler, less-humid environment and not subjected to extreme environmental changes should last longer
Storage temperature and relative humidity ranges recommended in various technical sources are presented in Table 3.. Table 3: Recommended storage parameters from different sources
CacaoRock: CD-Rot: It’s Happening [14]
Take a look at what I’ve been dealing with since approximately 1995:. Errol Garner’s Verve Jazz Masters 7 CD was always kept in a fresh and cool place
|Errol Garner’s Verve Jazz Masters 7 (1994) did not deseve this.|. |Nor James Brown’s Sex Machine – The Very Best Of CD (1991).|
In my collection, some of the CDs manufactured by Polygram in the United States had this disease. My Stan Getz’s Verve Jazz Masters 8 CD was in such a bad shape I had to throw it away, and I had to buy another copy of In The Court Of The Crimson King by King Crimson after the first song started to skip awfully

Help me understand “CD rot” [16]
The funny thing – CD “Rot” was a topic now 18 years ago, the linked article is from Friday, 27 August, 2004.. But the topic was never updated and though the articles predicted further detoriation, “rot” never became a topic again..
I saw a “rotten” CD once in a second hand record store, but that’s all.. I have a collection of about 800 compact discs, including the very first I bought in 1984:

What is ‘disc rot’ and will it eventually destroy video game collecting? — Steemit [17]
What is ‘disc rot’ and will it eventually destroy video game collecting?. One of the banes of video game, as well as other physical media collectors is the term “disc rot.” The words will send a shiver down the spines in those of us who have large collections of media on disc
Video games, DVDs/Blu-rays and CDs all work off the same technology. A disc imprints on a thin layer of plastic with millions of tiny dots in a spiral that circles the disc
A laser passes over these dots as the disc spins, reading the data. The disc player detects if the laser is reflected back; if it is, it reads a ‘1’, and not it reads a ‘0’.
Is disc rot something to be seriously worried about? [18]
Is disc rot something to be seriously worried about?. Many people have been mentioning disc rot lately and I wonder if it is something to be seriously worried about it.
Just trying to get an idea of what is normal and what to expect when rewatching older discs.. I store most of my collection in a cool and dark area, so I suppose that should reduce the risk of disc rot somewhat?
Plastic and aluminum are resilient for different reasons. In the case of plastic you have a chain made of carbons and if protected against moisture it is the same as the element that is aluminum…it simply isn’t going to break down at all
Disc Rot (yes this thread again): is there any point to investing in a collection of physical games? [19]
“Seriously though”Have you just never had a hard drive fail? No matter how well you take care of things they are eventually going to wear out. Most of my desktop hard drives have needed to be replaced after the 6 year mark
I hate to say it, but if your kids are anything like mine, they won’t be interested in the old games no matter how hard you try. I’ve tried for the last 6 years to get my kids(now 8 and 11) to play old games from the 8, 16, and even 32/64 bit eras, and they refuse, calling them ugly, boring, and too hard
As long as there are people with collections, there will be hardware. Everything will rot, degrade, and die, and digital services will end
The first generation of CDs is already rotting and dying [20]
Digital data itself can be duplicated an unlimited number of times without any generational loss – meaning it can theoretically last forever. But digital storage on physical media is subject to failure – and that failure can render the data inaccessible
And we’re already entering an age when one of the most popular formats is reaching the start point for common failures.. A report by Tedium (republished by Motherboard) demonstrates one of the most alarming failures
