from the Kodak Site: With KODAK’s announcement on January 24, 2002 that it is discontinuing its CD-R media products, it is no longer possible to place custom orders for Gold Ultima media.
Looks like Kodak CD-Rs are going extinct…
The Ultima Gold CDs have a writable side that is, well, gold colored, and the writable side on the silver-gold CDs is silver nor gold (but in between). The Gold CDs are better, hence they’re more expensive (and hence the lifetime warranty).
The Gold CD-Rs are my personal favorites, never had problems with 'em, even with CDs which I have used almost daily for two years.
