ABSTRACT OF THE DISCLOSURE An information recording medium for use with focused laser beams modulated with recorded information signals comprising a substrate having a recording layer composed of at least two layers, the first being formed on the substrate and the second being formed over the first. The substrate and the first layer have the property of high transmittance to laser beams and the second layer is composed of a metal which is predominantly a low melting metal capable of absorbing the laser beams and readily forming an alloy with the material of the first layer, the thickness of the first layer being such that the reflectance of the laser beams entering from the side of the substrate is lowered by the interference effect caused by repetitive multiple reflections. The metal of the second layer is thus alloyed to the first layer due to the focused irradiation of the laser beams from the substrate to the recording layer, changing the conditions for the multiple reflections and changing the reflectance in the recording layer as viewed from the substrate, thereby carrying out the recording of the information.
