Abstract
PURPOSE: To improve the molding property and shorten the molding time by a method wherein a signal having recessed and protruded shapes is transferred onto an ultraviolet-curing resin coated on a base sheet and ultraviolet rays are irradiated upon the resin to set it simultaneously with or immediately after this transferring.
CONSTITUTION: The ultraviolet-curing resin 51 is coated on the delivered base sheet 50 at a coating section 10 by means of roll coat or the like with a uniform thickness within a range of 10W100μm, thereafter, ultraviolet rays are projected by an ultraviolet rays lamp 12 of a precuring section 11 to make the resin into a half-cured state. This base sheet is introducecd into a press section 18 and the base sheet 50 having the half-cured resin layer 51 is pinched to transfer the signal of recessed and protruded shapes being possesed by a stamper 21. Immediately after releasing a pressing force of the press, curing is effected by ultraviolet lamps 24 to set the resin 51 completely. Subsequently, the disk is manufactured by punching at a punching section 26.
