DISK LAMINATING DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laminating device of an optical recording medium (disk), which can reduce warping of the disk with high precision when laminating. SOLUTION: This device has a means to irradiate the radiation ray from both sides to cure the disk after two plates are laminated and a means to shift the irradiation start timing for both radiations. This device is characterized in that it has a mechanism to control the amount of warping of the disk after curing.
