Abstract
A system for mounting a hub to an optical disk comprises a turntable arranged on an X-Y stage, a loading rod arranged above the turntable and extending vertically, a chuck provided at a lower end of the loading rod, for holding the hub with the axis of the hub aligned with a reference line as the axis of the loading rod, and a pair of displacement sensors for detecting a deviation of the axis of the turntable from the reference line, whereby the X-Y stage is driven in accordance with the signal from the displacement sensors, to position the turntable such that the axis of the turntable is aligned with the reference line. Thereafter, the optical disk is placed on the turntable with the axis of the optical disk aligned with the axis of the turntable, and the hub is placed on the optical disk through an ultraviolet-curing adhesive, by using the loading rod, with the axis of the hub aligned with the axis of the turntable. The system further comprises an ultraviolet radiation device for emitting an ultraviolet radiation onto the adhesive.
