摘要： The invention provides an optical recording medium comprising at least two recording layers containing a dye. At least two layers of the recording layers have different optical constants, and at least one among these recording layers having different optical constants contains a dye which forms a thin film having an absorption spectrum whose half-value width is up to 170 nm. This construction permits the medium to be written and read in a conventional wavelength range of about 780 nm and a shorter wavelength range of about 630-680 nm.

摘要： An optical recording medium having a recording layer and a reflective layer closely stacked on a substrate, wherein recording is carried out by directing recording light to the recording layer to form pits and reproduction is carried out by directing reproducing light to the recording layer. The recording layer contains a light absorbing dye, typically cyanine dye and a bisphenylenedithiol copper complex quencher in either independent form or ionically bonded form. The quencher characterized by a low coefficient of extinction can be added in a sufficient amount to provide the recording layer with light resistance while maintaining recording/reproducing performance.
