Optical recording information medium |
| abstract |
An optical recording medium comprising a recording and a metal reflective layers on a transparent substrate having a groove, wherein the recording layer comprises an azaporphyrin metal complex dye with 1 to 4 meso-nitrogen atoms as a main component; recording and/or reproduction can be conducted using laser beams with wavelengths of λ1 and λ2 which is shorter than λ1; a refractive index n of the recording layer is 2.0 or more at λ1 and 1.8 or more at λ2 as well as an attenuation coefficient k of the layer is 0.04 to 0.20 at λ1 and 0.30 or less at λ2; and the groove has a pitch of 0.70 to 0.85 μm, a half-value width of 0.20 to 0.35 μm and an inclination angle of 45 to 65 DEG. |
