Abstract
An optical recording medium manufacturing apparatus includes transfer means, a substrate transfer table transferred by the transfer means at a predetermined speed, a drum facing the substrate transfer table and rotating so that the speed of its outer circumferential surface is the same as the speed of a substrate transfer table, a stamp installed on the outer circumferential surface of the drum forming an information recording pit pattern, and resin supply means for injecting molten resin between the stamp and the substrate supported on the table. Since a multi-layer unit can be molded continuously by using the molten resin according to the present invention, there is the advantage of improved productivity.
