On December, I wrote about a couple of my concert music DVDs rotting away.
And the YT algo just popped this on the feed, talking about a number of Warner Bros titles that are apparently being affected.
Somebody on forums (!!! They still exist!) posted a list of probable affected titles, and to my dismay, the Greta Garbo and (both) Joan Crawford collections are affected. I just popped Mata Hari and Possessed on the player and seem to be playing fine.
Another one of the fears with (new) media and products that developed in types of plastic is that they’re decaying faster than people expected. I’ve had older (retired) players that were kept on storage that have a general sticky texture after a while. However, this doesn’t seem to happen to players that are in general exposure, not directly with sunlight, but in a generally airy room that’s in use, unlike a display room. I also happen to live in the mildest of climates, though high in humidity, temperatures never go above 30C (above 90F) or lower than 14C (lower than 55F). So maybe these conditions are affecting the storage of physical media.
I did the vast majority of my library collection before 2007, though. I did buy a number of things in between the mid-2000s to late-2000s, so if disc rot is affecting a general batch produced in between 2007-2009, it is a concern. I’m generally more worried with collections I keep in drawers instead of a regular shelf display.
