Provides nearly twice the capacity of conventional DVD discs by using two thin embedded organic dye films, which are separated by a semi-reflective layer and a spacer layer. Focused laser beam's heat causes irreversible change in the physical and chemical structure of each layer. New optical structure provides the right reflectivity for a sharp read out signal of the disc.
