Publication number: 20090109811Abstract: An optical disk apparatus driving an optical disk includes a tilt-angle adjusting unit configured to adjust a tilt angle indicating the tilt of an optical axis of laser light emitted from a pickup to detect an optimal tilt angle at which a traverse signal has the maximum amplitude and a storing unit configured to store information about the optimal tilt angle. When the optical disk has multiple recording layers on one side, the tilt-angle adjusting unit adjusts the tilt angle with respect to each of the multiple recording layers to detect the optimal tilt angle and the storing unit stores information about the optimal tilt angle with respect to each of the multiple recording layers. The tilt angle with respect to each of the multiple recording layers is controlled in accordance with the information about the optimal tilt angle with respect to each of the multiple recording layers.Type: ApplicationFiled: October 2, 2008Publication date: April 30, 2009Applicant: Sony CorporationInventors: Yasushi Tomita, Takamichi Yamakoshi, Kamon Uemura

Patent number: 6297931Abstract: A disc includes a disc substrate having a major surface operating as a signal recording portion and having a substantially circular center opening in the major surface, and a hub mounted on the disc substrate for closing the center opening in the disc substrate. The hub includes an inner rim portion having a spindle opening at its center and an outer rim portion connected to an outer side of the inner rim portion for extending from the inner rim portion via a step difference towards the side of insertion in the spindle opening. When the hub is set on a disc table, the outer rim portion protruded on the side from which the spindle is inserted into the spindle opening with a step difference approaches a magnet provided on the disc table to increase the force of suction by the magnet so that the magnetic disc is chucked with respect to the disc table solely by the force of the magnet.Type: GrantFiled: August 11, 1998Date of Patent: October 2, 2001Assignee: Sony CorporationInventors: Yasushi Tomita, Mamoru Oosato, Hiroyuki Suzuki
