Bit Rot

Bought a sealed copy of Windows 98 Second Edition last year and the disc has a dark spot on the data side, it installs and works correctly so I imagine it must be language packs and other useless optional crap on the far edge of the disc.

I've had a few discs like that, it seems the top coat seal isn't that good and the reflective layer is oxidising. If it gets bad enough it won't be readable. I've seen this happen on water damaged discs too.

Now I have to check the laserdiscs I have, I don't have a player but I've picked up a few discs somewhat recently. I'm hoping they're all right.
