Disc rot is the tendency of CD, DVD, or other optical discs to become unreadable because of chemical deterioration. The causes include oxidation of the reflective layer, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together.

CD degradation can be caused by mishandling or improper storage, but disc rot is typically caused by a chemical reaction with the reflective layer of the disc. What Is DVD Rot? Causes and Signs Explained. Though they look almost identical to CDs, DVD structure is a little different, using a plastic disc over the reflective layer.

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. This section covers the effects of environmental conditions and …

2005年6月26日 · Have any of you heard of DVD Delamination and/or DVD Rot? The way I understand DVD Delamination is that some dvds have been poorly manufactured and after time there is a separation of the layers on the disc which cause the disc not to play.

2024年7月31日 · HD DVDs, like other optical media, can be susceptible to disc rot, especially if they were manufactured with lower quality standards. Delamination: The layers of the disc can separate, leading to similar problems as disc rot. This can be caused by environmental factors such as humidity and temperature fluctuations.
