Abstract
There is provided a method of producing a multilayer optical recording medium through which the occurrence of burrs is reduced. The method of producing a multilayer optical recording medium includes, when a UV curable adhesive is interposed between a first disk and a second disk, the first disk and the second disk are rotated, and when at least one of the vicinities of inner circumferential edges and the vicinities of outer circumferential edges of the first disk and the second disk is masked with a mask member, emitting ultraviolet rays for preliminarily curing the UV curable adhesive from the side of a light emission surface of the first disk during rotation.
