Patent number: 8705327Abstract: An optical near-field generating efficiency of an optical near-field generating element is improved and a temperature rise of the element is suppressed.

Patent number: 8705323Abstract: TAR enable write heads may use a plasmonic device (e.g., an optical transducer) which uses electromagnetic energy generated from a laser to heat the magnetic media. However, as the temperature of the plasmonic device rises, the likelihood of stressing the material of the device or other materials of the head near the plasmonic device increases. Accordingly, the write head may include a temperature sensor proximate to the plasmonic device. In one embodiment, the resistance of the temperature sensor may change according to the temperature of the plasmonic device. Based on the measured resistance of the temperature sensor, a sensing circuit may adjust the power of the laser, and thus, prevent the stressing of the materials. Moreover, the thermal coupling between the temperature sensor and a heat sink connected to the plasmonic device may be improved by moving elements associated with the sensing circuit closer to a heat sink.Type: GrantFiled: December 21, 2012Date of Patent: April 22, 2014Assignee: HGST Netherlands B.V.Inventors: John T. Contreras, Fu-ying Huang, Lidu Huang, Takuya Matsumoto, Erhard Schreck, Barry C. Stipe

Patent number: 8630159Abstract: In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.Type: GrantFiled: July 17, 2012Date of Patent: January 14, 2014Assignee: Mitsubishi Electric CorporationInventors: Hironori Nakahara, Nobuo Takeshita, Masaharu Ogawa
