Whats the difference between TDK Gold and Silver CD-R discs?
For clarification, this question refers to the reflective surface, not the recording dye. TDK used gold for the reflective surface in its previous generation of CD-R: It had good reflective characteristics and was stable. However, new advances in technology led to using silver because, in conjunction with our cynanine-based recording dye, it greatly enhances reflectivity (the measurable amount of light bounced back to the laser). This means better compatibility with CD-ROM drives, even older drives whose laser sensitivity diminished with age.
