PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing an optical recording medium capable of forming a cover layer with a uniform thickness so as to prevent the generation of burrs or peeling. SOLUTION: A radiation curable resin material 18 is supplied annularly around a center hole 12 on a substrate 14 in a flowing state, a translucent circular covering member 20 having a center hole 22A, formed into a circular plate shape, and having an outer diameter smaller than the inner diameter of a recording area Ar is moved and mounted onto the resin material 18, the substrate 14 and the circular covering member 20 are rotated to make the resin material 18 flow outside in the radial direction by a centrifugal force to spread on the substrate 14, and a radiation ray is irradiated to the substrate 14 to harden the resin material 18, and then the circular covering member 20 is peeled off.
