An optical information recording medium is composed of a substrate, and a recording layer formed on the substrate, the recording layer including (a) a first recording layer, (b) an intermediate, and (b) a second recording layer, which are successively overlaid on the substrate, the first recording layer containing as the main component an organic dye having a peak of spectral reflectivity near the wavelength of a light beam for the recording and reproduction of information, the intermediate layer being transparent to the light beam for recording and reproduction of information, and containing a material having a refractive index smaller than the refractive index of the second recording layer, and the second recording layer containing as the main component an organic dye having a peak of spectral absorbance near the wavelength of the light beam for recording and reproduction of information, and having a thickness by which a maximum reflectivity is exhibited.
