PURPOSE:To adhieve the optical recording property, reading property and shelf life stability, by providing the colored electrolytic polymerized film coming in contact with a nonconductive substrate layer and the light transmitting sur face layer coming in contact with the polimerized film. CONSTITUTION:A copnductive base A and a counter electrode 2 are respectively connected to the anode 4 and cathode 5 of a d.c. power source 3, dipped in an electrolyte 6 and current is applied thereto within a fixed range of voltage for a fixed time. Thereby, a polymer 7 is uniformly deposited on the anode, base A according to the used quantity of monomer. The polymer 7 together with the base A is washed, dried, transferred by adhesion onto a support layer 1 or a surface layer 12 and an optical recording medium 8 is obtained. When a recording light 9 is irradiated as information is onto the medium 8, the optical recording layer, polymer on the support layer 1 discolors or changes in quality only in the exposed part 10. Therefore, when a faint light is irradiated on the recording surface, the recorded information can be accurately read by the absorp tion and reflection of light. |
