What Causes Cd Rot?

Generally speaking, disc rot occurs due to chemical reactions with the reflective layer of the disc, ultraviolet light damage, scratches that expose the delicate and corrosive layer to environmental factors, or the deterioration of manufacturing materials.

Can you fix disc rot?

A disc affected by CD rot cannot be repaired, it must be replaced. Fortunately this damage is rare and the manufacturer most affected by this has stated that it will replace any such CDs.

How does disc rot occur?

It is most commonly attributed to oxidation in the aluminum layers by poor quality adhesives used to bond the disc halves together. Poor adhesives separate over time, which allows oxygen in the air to corrode the thin aluminum layer into aluminum oxide, visible as transparent patches or small dots in the disc.
