PURPOSE:To obtain a thin disk by adhering disk substrates with recording films facing to each other to a supporting body which absorbs laser light. CONSTITUTION:The disk substrates 1 are adhered to the supporting body 2 which absorbs laser light to be used in a manner that the recording films face to each other. When laser light irradiates the disk, the light is absorbed by the supporting body 2 and never returns to the incident side nor transmits to reach the recording layer of the opposite side. The air gaps 3 can be enough minimized, and thus the obtd. optical disk is thin. |
