I suspect the contrary. There were initial claims that
CD's
would be nigh impossible to degrade, and the truth turned
out to be completely at variance with the assertions.
I don't remember those claims (although I wasn't paying all that much
attention to the subject at the time), who made them? Modern CDs are
far better than the early ones, as I understand it (although not good
enough for this purpose, even without the issue of needing a reader
for them).
I really think a proven track record counts in this
actual case.
Surely it would be useful to place those vellum records where
it is known they have in the past come to no harm.
How well proven is the track record for vellum? Lots has survived,
certainly, but how much didn't?
On the unconnected point of value of materials; really
it would
be much preferred if the material itself had as little intrinsic
value as possible.
That is a good point.
