Can't happen. Like regularjoe said, it was probably laser-rot.

Nope, wasn't laser rot at all. They where actually damaged by a cheap player ( cant remember the brand ) that actually ran hot quite often and it warped the discs enough for them to get scratched and that messed up the playback.

This happened way back in 1990 and I would have never thought that at the time, a laser disc could warp like it did in that player. I had a friend who had a cheap pioneer player that warped a laser disc of Predator because it also ran hot for some reason. I actually had a Johnny Mnemonic that suffered from laser rot.
