Here is what they say.... From Delkin: The World's Most Reliable CD. Delkin, manufacturer of quality eFilm memory cards and other innovative products, recently introduced the eFilm Archival Gold 300-Year CD-R. eFilm Archival Gold CD-Rs incorporate patented Phthalocyanine (thalo-sy-a-neen) dye and a 24k gold reflective layer in every CD-R. The innovative materials found in eFilm Archival Gold CD-Rs make them one of the most reliable storage medium available. Typically CD-Rs are known to deteriorate quickly due to ultra violet light, heat, and humidity. Using an accelerated aging process to test the longevity of CD-R media, eFilm Archival Gold CD-Rs have been shown to safely store your images for more than 300 years. Consumers are now taking more pictures than ever with digital cameras, explains Martin Wood, CEO of Delkin Devices, Inc. Our research has indicated that the number one reason consumers take digital images is to preserve their precious memories. eFilm Archival Gold CD-Rs ensure that your precious memories are safe for years to come. The patented Phthalocyanine dye is the most critical component of the CD-R because it is where your data is stored. Your CD burner creates pits in the dye layer when it burns a CD-R and your digital information is stored in these pits. The Phthalocyanine dye reacts quicker to the writing laser than dyes found in most CD-Rs on the market, thus making sharper pit edges and making your CD-R easier to read by CD drives. Compared to Cyanine and Azo dyes found in the majority of CD-Rs on the market, Phthalocyanine dye lasts significantly longer when subjected to the harmful effects of UV light, heat, and humidity. Gold is one of the most inert elements on earth and Delkin incorporates 20 of 24k gold into every eFilm Archival Gold disc. Golds inert characteristics prevent oxidation, a common cause of failure to most CD-Rs. Along with the Phthalocyanine dye and gold reflective layer, eFilm Archival Gold CD-Rs provide the most extreme protection for your digital images from environmental degradation. Very interesting to see if this is true. I would have to wait out for the DVD version though. :> TMG
