I have heard that Gold CD’s and DVD’s have been making a comeback. These are gold-layered discs, (important) not just gold-colored. They use a different technology in the production which gives them a much longer life-span, 100-300 years, instead of the usual 1-5. You can read about the whys and wherefores at Skana Imaging Solutions.
The better known brands are Kodak and Mitsui. They’re $2-3 each, less if you buy in bulk. The DVD’s are about the same price as the CD’s so obviously a better bargain if you have DVD-capability.
Here are a few links. The prices are changing as I write. You might also find them in earthly stores if you’re not living in the backwoods like me.
