Abstract
In a bonded optical disk comprising two base disks which are bonded together by UV-setting adhesive, one or two of the base disks are provided with a projection located inside the adhesive application starting position in order to maintain the distance between bonded surfaces of the base disks at a predetermined thickness for the adhesive layer. A mold for molding above base disks is also provided. The thickness of the UV-setting adhesive is easily held at a predetermined thickness by the projection located inside the starting position. Therefore steady mass production of bonded optical disks with uniform adhesive layer thickness is made possible with easier management of the adhesive layer thickness.
