Disc rot

Disc rot is a problem that can happen with CDs, DVDs, and other discs. It's like when food goes bad, except it happens to discs. When a disc gets disc rot, it can get tiny scratches, dents, and other wear and tear. The scratches and dents make it so the disc won't work right anymore, like it won't play the movies, songs, or other things that were stored on it. To avoid disc rot, it's best to keep your discs in a cool, dry place, and away from direct sunlight.
