ABSTRACT:
An apparatus for producing an optical recording medium in a sheet form, having a resin melt-extruding device that forms a resin sheet, a first heated roller having a predetermined unevenness pattern, and a second heated roller disposed opposite thereto. Further, the apparatus has a conveying device that conveys the resin sheet, in a substantially melted state, between the first and second rollers, which transfer an unevenness pattern to a surface of the resin sheet. The apparatus also has a temperature control device to gradually cool the resin sheet.
