Do they last more than 20 years in ideal conditions?
Optical discs are already incredibly resistant and shouldn't be expected to fail in your lifetime. Most of the times they do, it's either old media (cd and dvd both had physical flaws in design), damage, or mistakes in manufacturing.
There's really no reason for the discs to degrade. It's just stamped plastic.
Pressed optical discs will last a very long time. The lifetime of burned discs depends on the type of dye that's used to store the data. Many of the early CD-R's would get corrupted after a few years, but that was solved a long time ago.
And then unsolved as of late by manufacturers cheaping out.
