I think the tests and articles in question are talking about the stability
of the dyes used in the MAM-A (formerly Mitsui) CD-Rs.  I'd be less
optimistic about the stability of the polymers used for the disc substrate,
but I'm probably not going to be around in 100 years to find out.  Finding
CD drives to read the blasted things in 100 years is going to be enough of
a challenge.

That being said, when we get a data conversion job, the results go out on
MAM-A Gold discs and we've never had a complaint.   Since the media is such
a small part of the job cost, it's immaterial.

50 for $100 is a bit on the high end.  We buy ours from one of the media
wholesalers and pay less than $1.00 each in quantities of 100.  We also get
the PVC jewel cases for CDs that survive the rigors of shipping much better
than do the styrene ones.
