Abstract
PURPOSE: To improve a molding property and shorten the molding time of a meththod wherein ultraviolet-curing resin is coated on a base film and is cured by irradiated ultraviolet rays thereon, therafter, the layer of the resin is separated therefrom and is punched.
CONSTITUTION: The ultraviolet-curing resin 51 is coated on the base film 50 by a coating unit 10 to a uniform thickness, thereafter, the film is pinched between a stamper 15 and an impression cylinder 16 to transfer a signal having recessed and protruded shapes possessed by the stamper 15 by pressing the resin coated surface with the stamper 15. Subsequently, the resin coated surface is irradiated by ultraviolet lamps 17 under a condition that it is adhered closely to the stamper 15, then the resin formed with the signal of the recessed and protruded shapes is separated from the stamper 15, thereafter, the resin 51 is separated from the film 50. Subsequently, the resin 51 is punched into a disk shape by a punching unit 21 to manufacture the disk.
