Optical information recording medium, method for producing the same, and method and apparatus for recording/reproducing information thereon abstract |
| abstract |
An optical information recording medium includes a first information layer 2, a separating layer 3, a second information layer 4 and a protective substrate 5 in this order on a transparent substrate. The second information layer comprises an optical interference layer 6, a lower protective layer 7, a recording layer 8, an upper protective layer 9, and a reflective layer 10 in this order from the side near the transparent substrate. The reflective layer has a refractive index of at least 2.5 at a wavelength λ of light beams 11. The second information layer is a reflectance-increase type where the reflectance with respect to the light beams incident from the transparent substrate side after recording is higher than that before recording. It is possible not to provide the optical interference layer 6 if the ratio n1/n2 of the refractive index n1 at the wavelength λ of the recording layer before recording to the refractive index n2 thereof after recording is not more than 0.8. |
