造装置。[Claims for Utility Model Registration] It has a stamper, a transparent substrate placed opposite to the stamper, a pressure plate and a center pin that press the back side of the transparent substrate, Manufacturing of information recording disks by pressurizing fluid-filled ultraviolet curable resin from the transparent substrate side to expand it to a predetermined external shape, and then irradiating the resin with ultraviolet rays from outside the transparent substrate and curing it to manufacture information recording disks. In the apparatus, a detector is provided on the surface of the pressure plate on the side that contacts the transparent substrate and detects the arrival of the resin at a predetermined final contour position where the ultraviolet curable resin is pushed and spread; An information recording disk manufacturing apparatus comprising: means for releasing the pressure applied by the pressure plate and the center pin to the transparent substrate in response to a resin arrival detection signal outputted by the apparatus.
