Even better, but harder to find in local shops, are Mitsui Gold CD-R's.
Kodak used to make true gold CD-R's, then they went to a gold alloy, then
they stopped making CD-R's altogether. I have a pallet-full of their
gold and gold alloy ones.
Mitsui Gold's are readily available by mail order, for like $80 per 100.
