That sounds to me like what was determined back then about "WORM"
technology, which, BTW, was used in the F-16, but I never heard it applied
to CD's. WORM media used an organic emulsion which, under the right
circumstances could deteriorate over long periods. I'm not convinced that
the encapsulated aluminum-film CD's we use today are subject to those same
concerns. Of course, I'm not certain the story you heard is the same one I
heard, either.
