The new Kodak Preservation series of CD-R and DVD-R promises data
storage of 80 to 300 years.

In all seriousness, while I don't really know what to make of Kodak's
claims for its new line, I do know that Kodak did at one time make the
best quality CD-R's on the market and commoditization essentially forced
them out. Kodak did not, like most others, opt to lower its standards
and compete on price, so the big box stores (which often use extra-cheap
or even free CD-R offers as loss-leaders) stopped carrying Kodak CD-Rs.
As for the others, AFAIK the discs manufactured by Taiyo Yuden are
generally regarded as the best of the rest. Many think highly of
Mitsui. The former are manufactured in Japan, I'm not sure about the
latter. Many people simply make sure that they only buy discs made in
Japan, but it can sometimes be hard to find them. More often, you'll
find discs made in Taiwan or Mexico. There actually aren't very many
places in the world where CD-Rs are manufactured, and almost all CD-R
brands (Sony, Maxell, Philips, Memorex, Verbatim, FujiFilm, etc., etc.,
as well as no-name brands) are manufactured at the same handful of
factories. Sometimes the same brand uses multiple manufacturers -- I
used to buy FujiFilm CD-Rs made in Japan by Taiyo Yuden, but I also
found lots of FujiFilm CD-Rs made in Taiwan. You have to read the
So whatever one makes of Kodak's claims, I'm glad they are coming back
and I will give these discs a shot as soon as I find a good source for
them. Give me a call in 80 years and I'll let you know how it's going!
