PURPOSE:To easily sweep away ultraviolet setting resin to be stuck to a roller by pressurizing a disk substrate, to which the ultraviolet ray setting resin is applied, to a stamper forming uneven patterns by the roller which surface is composed of silicone rubber. CONSTITUTION:A transfer part 3 of a disk manufacturing device 1 is composed of a stamper holder 11, which holds a stamper 10 forming the minute uneven patterns on the surface, and a roller 12 to pressurize a disk substrate 6, to which ultraviolet ray setting resin 9 is applied, to be adhesively loaded onto the stamper to the stamper 10. For the roller 12, a pressure part 20 composed of the cylindrical silicone rubber is provided on the outer peripheral surface of a turning shaft 19 composed of stainless metal, etc., for example. Thus, even when the ultraviolet ray setting resin 9 protruded out of the disk substrate 6 is stuck to the pressure part 10 for pressurizing the disk substrate 6 and the stamper 10, the ultraviolet ray setting resin 9 can be easily swept away and productivity can be improved. |
