FIG. 1 is a diagram showing the configuration of the ultraviolet irradiation device in this embodiment, and the components having the same functions as those in FIG. 2 are designated by the same reference numerals. 5 is a motor for rotating the stage, and 6 is a feed screw. A feed motor 7 reciprocates forward and backward to linearly reciprocate the stage 3.

紫外線硬化樹脂が得たエネルギ量によって定まる。First, when a stamper, a substrate, and an ultraviolet curable resin are set on the stage 3 and the ultraviolet irradiation lamp 1 is turned on to manufacture an information record carrier, the stage 3 is rotated by the stage rotation motor 5. A linear reciprocating motion is performed by the feed motor 7. Generally, it is a linear light source of the ultraviolet irradiation lamp 1, and it is impossible to uniformly irradiate the entire surface of the disc-shaped information record carrier. In order to manufacture a highly accurate information recording carrier, it is necessary to keep the curing shrinkage ratio of the ultraviolet curable resin constant on the entire surface of the disc. The cure shrinkage is
It is determined by the amount of energy obtained by the ultraviolet curable resin.

強弱のある部分を移動するため、ある一定時間の中では
照射エネルギは載物台上全面で平均化される。By rotating and linearly reciprocating the stage 3, at each point on the stage, the illuminance varies at a certain moment, but the movement draws a complicated locus to move the part where the illuminance is strong or weak. Therefore, the irradiation energy is averaged over the entire surface of the stage within a certain period of time.
