Laser rot is caused by oxidation of the aluminum reflective surface due to air seeping into what is a sandwich of two polycarbonate discs that are glued together. The result can be a whole range of visible defects, typically "snow" (big multi-colored particles), weird streaks, etc. I suppose DVDs, CDs, SACDs, etc could "rot", but I have never encountered this phenomenon in these products; I've see a lot of rot in laser discs, and I'm not just talking about the state of Hollywood film-making.
