CD-R recording dyes (formulations) come in the 3 basic colours: Colourless (Pthalocyanine) – which may appear as gold or silver depending on the reflective surface Green or Blue-Green (Cyanine) Blue (Azo) Each has specific attributes. Cyanine, used for TDK media, has a wide power margin: the recorder’s laser power can vary to a greater extent from optimum and produce discs with good signal characteristics. The bluish-green colour of TDK’s current media is due to the silver reflective surface; the dye is still Cyanine-based.
