STICKING METHOD AND DEVICE FOR OPTICAL STICKING TYPE DISK

PROBLEM TO BE SOLVED: To provide a sticking method and device for optical sticking type disk by which the upper side disk can be brought into contact uniformly with an adhesive on the lower side disk without damaging the recording area of the disk. SOLUTION: This device for producing an optical sticking type disk by sticking two upper and lower disks is provided with a means 13a, 14a for each sucking and holding on a planer member a disk retention part inside such a ring-shaped projection 15 for integration that is formed on the surface of the two disks 2, 3; a means 13b, 14b for each sucking and holding on a planar member at least a part between the outside of the ring-shaped projection 15 and the inside of the recording area; and a means 13, 14 for bringing the upper disk 3 into contact with the adhesive 7 discharged on the lower disk 2, with the two disks 2, 3 sucked and held. Since sticking is possible with the upper and lower disks reduced in camber, air bubbles can be prevented from being mixed inside the adhesive layer.
