What is “DVD rot?
DVD rot makes discs unplayable by impairing the ability of their aluminum layer to reflect light. Its most likely causes include oxidation caused by air coming into contact with the reflective layer, a galvanic reaction between a dual-layer disc’s gold and aluminum coatings, and a chemical reaction triggered by impurities in either the disc’s adhesive or in the aluminum itself. The vast majority of reported cases of DVD rot have been shown to be due to poor quality control during the manufacturing process or user mishandling. DVDs are a delicate audio/video/data storage device that is held together by a laminated outer surface containing layers of plastic and reflective metal coatings, and held together by special glues. If manufactured with proper quality control at the production line end, placed and removed properly from its storage case when used, and stored properly by the consumer, DVDs will definitely outlive their video tape counterparts.
