PURPOSE:To obtain an optical disk having a high reliability by opposing the first disk an the second disk, and connecting as one body the second disk side plane of the first hub and the second disk side plane of the second hub. CONSTITUTION:Two pieces of disks 3, 4 which ended a replica process are prepared, the second disk 4 is placed on a base 24, and by inserting a centering pole 25 through a center hole 13 of the second hub 12, the second disk 4 is positioned on the base 24. Subsequently, an inside periphery spacer 1 and an outside periphery space 2 are placed on the disk 4. When placing the inside periphery spacer 1, positioning of the inside periphery spacer 1 is executed. Thereafter, the first disk 3 is placed on the inside periphery spacer 1 and the outside periphery spacer 2, and also the centering pole 25 is inserted through the center pole 13 of the first hub 1. In this way, the first disk 3 and the second disk 4 are brought to centering at a correct position, and two pieces of disks 3, 4 and the inside periphery spacer 1 and the outside periphery spacer 2 are stuck as one body. |
