Lens position control method, lens position control apparatus, cutting method, and cutting apparatus
Patent number: 8085627Abstract: A lens position control method is disclosed. Either an objective lens or a master disc having a resist material film on its substrate is moved, thereby changing a distance between the objective lens and the master disc surface. A return laser beam transmitted through the objective lens and reflected by the master disc surface is detected by a photodetector. The movement of either of them is stopped when the master disc is located near a focal point of the objective lens and the return laser beam is detected. Limit data is rewritten to data corresponding to a position obtained by adding a movement permission amount smaller than a working distance of the objective lens to the stop position. When the return laser beam is not detected, the movement which changes the distance between them is stopped at a position corresponding to the limit data.Type: GrantFiled: July 18, 2006Date of Patent: December 27, 2011Assignee: Sony CorporationInventor: Gakuji Hashimoto -
