摘要： An optical recording disk comprising a grooved substrate, a dye-containing recording layer, and a reflective layer in close contact with the recording layer is recorded by directing recording light to the recording layer in the groove to form pits and reproduced by directing reproducing light to the pits. The substrate is formed of a cyclic olefin polymer. A photo-stabilized cyanine dye in the form of an indolenine cyanine dye cation-quencher anion ionic combination has relatively constant values of n and k with a variation in the wavelength of recording/reproducing light. Then the disk is resistant against light, heat and water to ensure satisfactory performance according to the CD standard.
