- caseyohara 6y agoProbably survivorship bias as the only old CDs for sale today are in good shape
- lb1lf 6y ago-Still only anecdata, but I've been buying lots of music on CD since the late eighties, the oldest I know of was pressed in late 1983 sometime. (Which is only a year or so after the introduction of the CD anyway) In sum, some 3,800 CDs. I ripped them all a couple of years ago - I had problems with a handful, but EAC eventually got them all to disk. I examined the troublesome ones, but no (visual) signs of disc rot.
- simonblack 6y agoFactory-made CDs are duplicated by a physical process. Most bad CDs were made using an opto-chemical process. The chemical processes are pretty much reversible, leading to dead CDs. The physical processes are much more robust, as you'd have to deform the actual base plastic, like cooking vinyl LPs in the sun.
