Yup, and the longest lasting of those use a gold reflective surface.
Phthalocyanine dye is covered by Mutsui patents and only a very few
manufacturers are licenced to produce optical disks using it. The only
No. American manufacturer is MAM, which claims "Accelerated aging tests
show that MAM Gold can be used as a reliable storage media for more than
300 years." Of course, none of us are likely to know if they are right
or not. :-) Not cheap compared to the mass market, but may be a
bargain for long term storage at $1.35 @ in bulk. Even if they don't
last 300 years, they should certainly last long enough to outlive CDs as
storage devices and be happy to pass their contents on to the replacements.
The same folks are making DVDs using the same dye and reflective
surfaces, although I don't think results are in yet on DVD accelerated
aging tests <http://store.mam-a-store.com/standard---archive-gold.html>.
If they can make reliably long lived DVDs, I would much prefer to use
them for my archival storage.
