A friend of mine told me once that his company had archived some 
customer data on CD-R, but years later they found that the CDs were
de-laminating.  Has anybody here ever experienced this?  

I don't know what brand he used, and I don't know if the bad CD-Rs were 
all from the same lot, so my evidence is fairly limited...  The oldest 
CD-R I have in my possession is probably only 3 years old.
