A method of manufacturing an optical information recording medium that has a substrate having a signal recording layer formed on one principal surface thereof; and an optically transparent layer formed on the signal recording layer and made from a radiation cure type resin. According to the method, when the optically transparent layer is formed, the radiation cure type resin is supplied onto the substrate, and the radiation cure type resin is applied over the substrate by spinning the substrate at a predetermined number of application revolutions in a spin coating method. The number of revolutions of the substrate is increased after the application of the resin, and radiation is irradiated to cure the radiation cure type resin while the number of revolutions of the substrate is increased.
A method of manufacturing an optical information recording medium including a substrate having a signal recording layer formed on a principal surface thereof and an optically transparent layer comprising a radiation cure type resin formed on the signal recording layer, the method comprising:
