With respect, Doctor:  Yes and no.  It really depends upon which CD-ROM
you're using.  I, too, have seen studies that state that some CDs (such as
the standard audio CDs on the market) will begin to lose data integrity in 10
to 15 years.  But this is not the case with gold-based CDs that have a
special coating (such as those being marketed by Kodak and several other
manufacturers).  The major problem (aside from scratches, etc.) seems to be
oxidation.  The sealant retards this process and gold doesn't rust.

There are a number of CD-ROM brands on the market, and they are not all
created equal.   There is a reason why some of the CDs at CompUSA et. al. are
priced at $.75 and why some are $2.  As is the case with many things, you get
what you pay for.
