Abstract: PURPOSE:To improve corrosion resistance of an optical recording medium having an optical recording layer by providing a protective layer consisting of a rare earth metal adjacently to the recording layer. CONSTITUTION:An undercoating layer 22, the protective layer 23a consisting of the rare earth metal, the optical recording layer 24 and the protective layer 23b consisting of the rare earth metal are provided on a writing side substrate 21a consisting of plastic, glass, etc. and a spacer layer 25 and a reflecting layer 26 are provided thereon. The protective layer is formed of the rare earth metal such as Sm, Gd, Tb, Dy and Ho or the alloy thereof. Since the rare earth metal is extremely easily oxidized, said metal incorporates positively the oxygen and moisture contained in the other auxiliary layers, etc. into said metal, by which the metal itself is oxidized to prevent intrusion of the oxygen and moisture into the recording layer, thus the layer consisting of such metal acts as a protective layer. The thickness of the protective layer consisting of the rare earth metal is adequately 20-50<-1>. If the thickness is smaller than 20<-1>, the oxidation expands to the recording layer through the protective layer, thus failing to provide the desired effect.
