[QUOTE=negritude;2100619]Interesting. I’ve only seen that kind of topside color change with improperly stored media, for example, media that sits directly in exposed light for years on store shelves…[/QUOTE]
Yes but these 5 disc’s were stored differently.
2 on a spindle.
1 in a binder
1 in a papersleeve
1 in a DVD type jewelcase.
There seems to be no pattern.
If it was just the sleeve one or the spindled ones then I might think light exposure. But the odd thing is that the disc’s on the spindle have disc’s of the same batch below and above them, which are still good.
Like said earlier, no real pattern. Except that the disc’s that become yellow are problematic.
