Defective 3M laserdisc

Archived from groups: alt.video.laserdisc (More info?)

I have a 3M copy of Grace Jones - State Of Grace. It has a lot of dropouts.
I see what appears to be dust on part of the disc. On close examination,
with a magnifying glass, I see what looks like small pits on the plastic,
but are actually in the plastic below the surface. This is a one sided disc
with a white plactic reverse instead of the usual "nothing on this side"
images. I have never had a 3M disc with laser rot before and don't know if
this is truely laser rot of some othe type of defect.
