The most permanent CD/DVDs are "gold" and use a special long lasting dye (I can't remember the chemical name right now). All CD/DVDs have a dye layer which is what the laser "burns." The usually gold or silver layer you see is a protective coating on the dye layer, and gold (real gold) is the best and expensive, but provides the best protection for the dye layer. So the longest lasting CD/DVDs have a best dye layer and a best protective layer. The long discontinued Kodak gold CD-Rs were some of the best and much sought after and expensive. inljetart.com used to carry CD/DVDs similar to the Kodak ones, but a quick look at their web site doesn't show them any more. I had some music CD-Rs I burned on cheap disks and within a year they were junk with the sound all garbled. Fortunately I stocked up on 50 of the Inkjet Art CD-Rs to use instead!

Yes I have. I started getting unreadable CDs from another photographer
in town--they were five to six years old. He had hundreds of these
backup disks and when he checked, many of those were unreadable as well.
He had difficulty explaining the loss to his clients.
I suggest hard drives. I have four backup drives in my studio and each
backs up to another every hour. Has been working well for several years.
