I found a newly reseased NIST "stability" study here:
http://www.itl.nist.gov/div895/gipwg/

A conclusion stated implies

"Samples containing phthalocyanine
performed better than other dye types. In
particular, phthalocyanine combined with a gold-silver
alloy as a reflective layer was consistently more stable
than all other types of CD-R media."

another conclusion is:

"Results suggest that these media types
will ensure data is available for several tens of years
and therefore may be suitable for archival uses.
Unfortunately, it is very difficult for customers to identify
these more stable media."

Does anyone recognize the media type relative to manufacturer? (Not necessarily Brandname)
