It's a rumour. Nice marketing ploy, however, ought to make the
department store some money.
Hold a CDR up and look at it from the side, notice how thick the base
layer is. The ink solvent evaporates immediately, and won't touch it.
The ink itself does not have enough of anything to do so either. Just
what is going to eat through the base layer?
Before the ink eats through it, you won't have anything to play it. Even
if that's hundreds of years.
