- There was a video store that I used to go to that up until a couple years
- ago had its rental video discs on display WITHOUT ANY PROTECTIVE COVERING
- at all. Just bare-naked discs stacked on-edge, sliding and scraping against
- each other. I was appalled (and I'm glad they stopped the practice), but
- amazingly most of the discs seemed to survive this unnecessarily brutish
- treatment, even though they began to look like they had been used as
- doormats.
-
- Under more reasonable conditions, I would expect a disc to hold up much
- longer than a tape. One rare exception: Years ago, a number of discs were
- produced with contaminated glue binding the two havles of the discs
- together. (LDs are built a bit like a CD-sandwich with glue filling.) The
- bad glue caused the aluminum signal-layer coating to slowly oxidize over
- time, which resulted in increasing video noise -- the condition was
- jokingly referred to as "laser rot". This has not happened in a long time,
- and the manufacturer (I think it was Pioneer) will still replace any disc,
- no matter how long ago it was purchased, if it displays this problem.
