ABSTRACT:
A method for producing an optical recording medium, includes: filling a plurality of spaces with a liquid photosensitive material, wherein each of the plurality of spaces is surrounded by a surface of a sheet material and partition walls that are formed on the surface of the sheet material for separating a plurality of recording areas, and the surface of the sheet material has recessed parts at positions where the plurality of recording areas is to be formed, each of the recessed parts protruding and deformed to a back surface side of the sheet material so as to have a volume in relation to a volumetric shrinkage factor of the photosensitive material; and pressing a member having a substantially flat surface to a back surface of the sheet material to make the recessed parts substantially flat and heating and hardening the photosensitive material to form the plurality of recording areas.
