An optical information recording medium includes a substrate and a recording layer arranged on or above the substrate, configured to bear recording marks upon irradiation of energy beams, and containing a tin-based alloy. The optical information recording medium further includes at least one dielectric layer adjacent to the recording layer, and the at least one dielectric layer mainly includes at least one oxide of an element selected from silicon, magnesium, tantalum, zirconium, manganese, and indium.
