ABSTRACT:
The present invention relates to a method of manufacturing an optical information recording medium, which forms a light-transmitting layer made of a radiation curing resin on a substrate having a signal recording layer, a liquid foundation is formed by coating the radiation curing resin in a first coating step. Next, a radiation curing resin is further coated on the foundation in a second coating step. After this, a curing step is performed. By separating the dropping and spreading of the radiation curing resin into two steps, not only the manufacturing time can be reduced, but also the volume of the used radiation curing resin can be reduced.
