Disk bonding apparatus and disk bonding method |
摘要 |
It is an object to provide an optical recording medium (disk) bonding apparatus which eliminates the warpage of a disk during bonding and has high precision in the bonding. There are provided means for bonding two substrates and then irradiating radioactive rays from both sides of the substrates when carrying out radiation curing, and a mechanism for shifting the irradiation starts of both radioactive rays to control an amount of warpage of each substrate after the curing.
