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.

Subject: Archival CDs
Hello, can anyone "confirm or deny" this?
<grin>
the
Am I mistreating archival CDs in the first place?
Supposedly, the US military did a study in the late 1980's to determine best archival mediums for the long haul. This concerns
military secrets
and
other issues of national security. CDs were originally
considered to be
the
easy winner, but when subjected to the accelerated
aging process, it was
found that a standard aluminum CD could only be trusted with 100% data
integrity for about 35 to 40 years.
Most interesting, was the supposed conclusion of the study, which ened up
selecting paper punchcards as the ultimate archival medium, lasting a
minimum
of 300 years when properly stored. Well imagine that.
Am I the only one to have heard this story?
