If you scratch the disk (crumbs/grit between magnet and disk) that might have done it.

A recorder encodes (or burns) data onto a recordable ... disc (called a blank) by selectively heating parts of an organic dye layer with a laser. This changes the reflectivity of the dye, thereby creating marks that can be read like the pits and lands on pressed discs.
For rewritable ... media, the laser is used to melt a crystalline metal alloy in the recording layer of the disc.
