摘要：
A process for producing an optical recording medium, including the steps of: melt-extruding a resin to form a resin sheet; passing the resin sheet under pressure between a first roller having a predetermined unevenness pattern and a second roller disposed opposite thereto before the resin sheet is hardened, thereby to transfer the unevenness pattern to a surface of the resin sheet; and forming a recording layer having an organic coloring matter on the surface of the resin sheet provided with the unevenness pattern; wherein the steps are conducted while the resin sheet is moved.
