I've been told that there is a vast difference in the containment/seal
of CDs made my record companies and those we burn at home. The former
provide a far closer perfect seal for the aluminum substrate, so that it
is far less likely for oxygen and fungus to get at it. In the case of
home-burnt CDs, the seal is far from perfect and by its very nature,
burning through the clear plastic finish means that oxygen (and yes, evil
fungii) can far more easily get at that aluminum.

I've also been told about home-burnt CDs where the aluminum substrate has
benn almost completely oxidised and/or eaten by fungus, leaving a mostly
clear plastic disc.
