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.
Also, the disc itself can be repaired. There are various machines that will repair discs by polishing, buffing or grinding the playable surface. Usually the disc will appear like new and most importantly the data can once again be read by the laser. Some game shops, pawnbrokers and supermarkets provide a disc repair service.
