PURPOSE:To form a fine pattern with good contrast by exposing a photosetting resin layer through a pattern of guide grooves and priformats to form an exposure part applying a dye solution on the substrate including the exposed part, and drying it to form a recording layer. CONSTITUTION:A card-type optical recording medium is formed on a solvent- resistant substrate 1, said recording medium including dye medium with guide grooves and priformats formed by the differences of reflectance. In this process, first the photosetting resin layer 2 is formed on the substrate 1, and ten exposed to light 4 through a photomask 3 the pattern of which includes guide grooves and priformats to form the cured part 5. After removing the unexposed part, the dye solution is applied on the substrate including the exposed part 5 and dried to form the recording layer 6. Therefore, monomers remaining in the photosetting resin after cured and the dye react in the interface of the photosetting resin layer 2, which reduces the reflectance of the dye. Thereby, the fine pattern with good contrast can be mass-produced at low cost. |
