|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-R's 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-R's on the market, Phthalocyanine dye lasts significantly longer when subjected to the harmful effects of UV light, heat, and humidity.
Thirty percent of the cost to produce a Delkin Archival Gold disc is due to the use of 24 karat gold - one of the most inert elements on earth. The unique characteristics found in Gold prevent oxidation, one of the most common causes of CD-R's failure. The combination of Phthalocyanine dye and the use of gold in the reflective layer of the disc ensure that Archival Gold CD-R's provide the most extreme protection for your digital images from environmental degradation.
