Abstract: A laser information recording medium comprising a substrate, a reflective layer and a recording layer. The recording layer is made of cumulative sub-layers of J-aggregates of an organic dye having an absorption band in the wavelength range of oscillation of the laser and an anionic film-forming material. The cumulative sub-layers may be formed by the Langmuir-Blodgett thin film method. The recording layer may also consist of a plurality of layers containing organic dyes having different absorption peaks of wavelength in their respective sub-layers. The organic dyes are preferably cyanine dyes of a specific type and the cationic film-forming material is preferably a mixture of at least two members of the group consisting of dioctadecyldimethylammonium chloride, octadecylamine and methyl stearate.
