Abstract

PURPOSE: To inhibit contraction due to the heat of polymerization in case of the hardening of ultraviolet hardening type resin and prevent the generation of a drop- out in case of regeneration due to the distortion of a high-density information carrier by mounting a cooling mechanism to a drag supporting a stamper.
CONSTITUTION: A cooling pipe 10 is disposed to a drag 1, and cooling water is passed into the pipe 10. The cooling pipe 10 is arranged to a lower section of a surface (a concave section 3), onto which at least ultraviolet rays are irradiated, annularly and at regular intervals. Contraction due to the heat of polymerization in the case when the ultraviolet hardening type resin of a disc material is subject to the irradiation of ultraviolet rays from an ultraviolet irradiating device 21 and hardened causing bridging can be inhibited extremely.
