I have had unbranded generics that went flakey or developed bubbles that eventually popped just a few months after burning. I am told that they were uncoated - cheaper (15 cents each) but won't last as long as branded ones. The substrate appears to be a kind of dehydrated organic gel which is sandwiched between a reflective dye layer and the clear plastic disk. A classical music CD set I bought 15 years ago started to develop punched-out holes in the substrate rendering them useless. I heard of a Spanish website that described a certain fungi that attacked CDs. >> Why can't they make metal disks like >> the ones inside the harddrive available?

DVD-Rs come single or multi-layered but seem to be pretty much made up of the same materials. Charlie -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
