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.

A method of producing a multilayer optical recording medium, comprising:
- 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 vicinities of inner circumferential edges and 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 a side of a light emission surface of the first disk during rotation.
A device for producing a multilayer optical recording medium, comprising:
- an emission member that emits ultraviolet rays;
- a holding unit that holds a first disk and a second disk that are laminated;
- and
- a mask member that masks at least one of vicinities of inner circumferential edges and vicinities of outer circumferential edges of the first disk and the second disk,
- wherein, when a UV curable adhesive is interposed between the first disk and the second disk, the first disk and the second disk held by the holding unit are rotated, and
- wherein, when at least one of the vicinities of the inner circumferential edges and the vicinities of the outer circumferential edges of the first disk and the second disk is masked with the mask member, ultraviolet rays for preliminarily curing the UV curable adhesive are emitted from the emission member from a side of a first main surface of the first disk during rotation.
