Abstract
Optical information recording medium comprises: a plurality of recording layers, each of which undergoes a change in refractive index by irradiation with recording beam; and an intermediate layerprovided between recording layers. The recording layercontains polymer binder and dye dispersed in the polymer binder, and at least in proximity to an interface (far-side interface) between the intermediate layerand a recording layerdisposed adjacent to incident side of the intermediate layerfrom which the recording beam enters the intermediate layer, the intermediate layerhas refractive index different from that of the recording layer. Glass transition temperature of the polymer binder is lower than melting point and decomposition point of the dye, and refractive index of the polymer binder changes by receiving heat generated when the dye absorbs the recording beam, whereby information is recordable in the recording layer.
