    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.
