Abstract

PURPOSE:To realize not only a high-accuracy optical information recording medium but a manufacturing process having a low cost and excellent productivity, by forming the record layer on the single side of the optically transparent high molecular film and adhering the film to the substrate with the record layer set at the inner side of the substrate. CONSTITUTION:The tellurium thin film 14 functioning as the record layer 3 which can be varied by the optical energy is formed on the lower face of the optically transparent high molecular film 11 functioning as the transparent protecting layer 4. The film 11 containing the film 14 is cut into a proper size, and the film 14 is set to the top force 15 of mold for the compression forming machine to oppose to the bottom tool 16. At the same time, the substrate 2 is set on the die 16 with the adhesion layer 17 formed on the upper surface of the substrate 2. After this, the top force 15 and the bottom tool 16 are pressed to each other to be stuck together. Then the adhesive layer 17 is taken out of the metal mold after being hardened, and the center hole 5 is blanked. Thus the optical information recording medium 1 is obtained.
