AFAIK, there are no aluminum based CD-Rs, the silver-looking ones actually have silver or silver alloy reflective layer.

- jacquesm 4y agoNot as far as I'm aware, it is a very pure aluminum layer. The real weak spot is the edge of the sandwich, especially if there is some form of thermal cycling, that can cause delamination to a degree that it will let a little bit of air in. Maybe I'm mixing up CD-R and CD-RW? The effect of corrosion on silver would be much the same as with Aluminum though, the silver would lose its reflective capabilities and that would show up as data corruption. I'd definitely still go with the gold version.
