I'm not sure if it counts as disc rot, but I have a double CD album (The
Orb - Live 93) that slowly became unplayable despite being kept well,
in their original jewel case.
What happened with these CDs is that the dye label (which covered the
whole of the label side) started flaking off, taking the reflective
aluminium layer underneath with it. Eventually I ended up with just a
couple of clear discs of polycarbonate, all the data still on them, but
completely unreadable by anything.
As an experiment I sprayed the label side with silver paint and tried to
rip the audio with cdparanoia (if you were using Windows I expect EAC
would work)... and it worked! There were a heap of minor read errors
but nothing that cdparanoia couldn't fix. It sounded dreadful when
playing in my CD player, but the data was off it, so I binned it and
burned it to CDR.
Which is great, at least for the next 10 years or so until significant
amounts of the recording dye migrate back to their original state, when
I'll have to salvage the audio all over again.
