PROCESS FOR PRODUCING OPTICAL RECORDING MEDIUM AND APPARATUS THEREFOR

摘要

An optical recording medium is produced in which air trapping or air bubbling in a resin layer is suppressed, and the resin layer formed has a uniform thickness. A disk cap member 9 having an diameter greater that the diameter of a central hole 2 of a circular substrate is placed on a recording medium 1 provided with the circular substrate so as to close the central hole 2, while a resin film A prepared by curing a liquid resin material a that covers a step formed by the cap member 9 and the recording medium 1 is formed. On the cap member 9, a curable resin material c for forming a resin layer 11 is supplied, and the recording medium is rotated to spin-spread the curable resin material c . During or after the spin spreading, the curable resin material c is cured so that the resin layer 11 is formed on the recording medium 1.
