    摘要： An information recording medium comprises a substrate and a recording film layer thereon comprising a hydrocarbon polymer and finely-divided particles of a metallic component dispersed therein, which recording film layer is a plasma polymerized film prepared by subjecting an organic metallic complex containing a center metal to glow discharging decomposition. The metallic component in the recording film layer may be a metal, a metal oxide or a composition of a metal and a metallic oxide. When a metal is employed as the metallic component in the recording film layer, information is recorded by applying laser beams thereto to form protuberances on the recording film layer corresponding to the recorded information, while when a metallic oxide or a mixture of a metal and a metallic oxide is employed as the metallic component, information is recorded by applying electron rays to reduce the metallic oxide to the metal to produce a recorded area and a non-recorded area having different reflectivities on the recording film layer, and the recorded information is erased by subjecting to the recording film layer to a heat treatment, so that reversible recording and erasing of information can be attained.

    摘要： A phase-change type optical information recording medium is disclosed, which medium comprises a substrate and a recording layer formed thereon. The recording layer comprises a phase-transition type compound consisting of 4 to 6 elements, having a chalcopyrite structure, represented by the following formula (I):X.multidot.Y.multidot.Z.sub.2 (I)wherein X represents one or two elements selected from the group consisting of elements belonging to the groups Ib and IIb in a periodic table; Y represents one or two elements selected from the group consisting of elements belonging to the groups IIIb, IVb and Vb in the periodic table; and Z represents one or two elements selected from the group consisting of elements belonging to the groups Vb and VIb in the periodic table.
