had this info tucked away pertaining to DiscoVision LDs
LaserRot:
Cause: Various
After some in depth research, my stand on LaserRot and DiscoVision has changed. LaserRot is a term coined during the early 80s as a way to describe a LaserDisc, that upon purchase, played very well, but then over time would develop video speckles and possibly audio noise. From the beginning, DiscoVision engineers struggled to determine why the quality of the discs were failing. Product would leave the warehouse having been quality checked only to be purchased by a consumer and returned as defective.
The gamut of defects due to laserrot vary. Some discs have developed light speckling at the beginning or the end of a side. Some sides develop a speckling pattern which stays constant through the entire length of a side. Still others deteriorate to the point that there is no visible picture at all and the audio is just a jumble of frequencies that doesn't even qualify as static.
The original statement made here DiscoVision discs do not rot is not true. Part of what has been discovered is that the discs did rot, but they would reach a rot threshold and the deterioration of the discs would stop. Some believe the discs would rot during the discs "curing" period - after which the level of rot would not increase. This is relatively far fetched because many discs would show the tale-tale signs of rot several months after purchasing.
That said, rot on DiscoVision discs is not progressive. Enough time has passed that any rot to develop on the discs would have done so by now. It's safe to say that the condition of your discs at this late date is the way they are going to stay when properly handled.
