20110007612 | Head gimbal assembly and information recording and reproducing apparatus - There are provided a head gimbal assembly and an information recording and reproducing apparatus capable of easily positioning a light guiding portion and a slider on a tongue portion and performing a stable recording and reproducing operation. A head gimbal assembly recording information on a recording medium using a near-field light includes: a suspension that extends along a surface of the recording medium so as to be deflectable in a thickness direction; a support portion that is provided at a tip end side of the suspension so as to be more deflectable in the thickness direction than the suspension; a light guiding portion that has a support-facing portion provided to the support portion so as to face the support portion and introduces a light flux used for generating the near-field light; and a 3-dimensional structure that is provided to the support portion and used for positioning the support-facing portion on a desired portion of the support portion, wherein the support-facing portion has a portion in which a width of a sectional surface thereof perpendicular in a longitudinal direction of the suspension is larger than a width of a contact surface that makes contact with the support portion. | 01-13-2011 |
20110075527 | Head gimbal assembly using near-field light and information recording and reproducing apparatus including the same - Of side surfaces of a flexible substrate provided on a flexure, one surface opposing an optical fiber forms a mirror surface inclined by a predetermined angle with respect to the longitudinal direction of the optical fiber. Owing to this configuration, the optical fiber is optically coupled to a near-field light element inside a slider. | 03-31-2011 |
20120063278 | Near-field light generating element, method of manufacturing near-field light generating element, near-field light head, method of manufacturing near-field light head, and information recording and playback device - A core includes a first core, and a second core covering a side surface of the first core, and is formed in a polygonal shape when viewed from a Z direction. A metal film is placed on a side surface in the core, and is formed so that a width of an interface between the metal film and the core is narrower than a width of the side surface of the core. | 03-15-2012 |
20120113769 | Recording head, method of manufacturing recording head, and information recording and playback apparatus - A near-field light generating element has a core that guides a laser light in a direction of a disk while reflecting the laser light, and a cladding that encapsulates the core in an inner portion, and lengths of a longitudinal direction and a transverse direction of an incident side end surface of the laser light in the core are formed so as to match the lengths of a long axis direction and a short axis direction of the laser light that is entered to the core. | 05-10-2012 |
20120206032 | METHOD OF MANUFACTURING NEAR-FIELD LIGHT GENERATING ELEMENT AND NEAR-FIELD LIGHT GENERATING ELEMENT - A U-shaped groove and a V-shaped groove are formed onto a cladding disposed on a substrate, a core and a metal structure are formed inside the grooves, respectively, and then the substrate surface is planarized. Further, after a cladding is formed again, the substrate is cut and the cut surface is polished such that the metal structure inside the V-shaped groove has a predetermined thickness, thereby forming a scattering body. | 08-16-2012 |
20120237797 | MAGNETIC RECORDING MEDIUM - A recording layer is formed on a substrate, and a high thermal conductor having a thermal conductivity higher than that of the recording layer is disposed inside a plurality of recording bit regions constituting the recording layer, respectively. Furthermore, the recording layer is formed with a separating portion which divides the recording layer into the plurality of recording bit regions. The separating layer is filled with a low thermal conductor having a thermal conductivity lower than that of the recording layer. | 09-20-2012 |
20150198562 | PIEZOELECTRIC UNIT, PIEZOELECTRIC DEVICE, PIEZOELECTRIC DETERMINATION APPARATUS, AND STATE DETERMINATION METHOD - A piezoelectric unit | 07-16-2015 |
20160077490 | MECHANICAL COMPONENT, MECHANICAL COMPONENT MANUFACTURING METHOD, MOVEMENT, AND TIMEPIECE - To provide a mechanical component, a mechanical component manufacturing method, a movement, and a timepiece allowing the forcing-in portion to be firmly fixed to the shaft member, providing a sufficient buffer effect, and capable of precisely determining the outer diameter dimension. Provided is a mechanical component rotating around a shaft member. This mechanical component includes: a component main body having a through-hole through which the shaft member is passed; and a forcing-in portion formed on the inner surface of the through-hole and fixed to the shaft member through the forcing-in of the shaft member. The component main body has a retaining recess constituting an anchor structure regulating displacement of the forcing-in portion with respect to the component main body. The forcing-in portion is formed of a metal material. | 03-17-2016 |
20160077491 | MECHANICAL COMPONENT, MECHANICAL COMPONENT MANUFACTURING METHOD, MOVEMENT, AND TIMEPIECE - To provide a mechanical component, a mechanical component manufacturing method, a movement, and a timepiece which are free from breakage due to the forcing-in of the shaft member and which allow the mechanical component to be reliably fixed to the shaft member. Provided is a mechanical component configured to rotate around a shaft member. The mechanical component includes: a component main body having a through-hole through which the shaft member is passed; and one or a plurality of shaft support portions formed on the inner surface of the through-hole and serving to fix the shaft member to the component main body. The shaft support portion(s) protrude (s) from the inner surface of the through-hole and is (are) capable of retaining the shaft member due to an elastic force. The elongation percentage of the shaft support portion(s) is larger than the elongation percentage of the component main body. | 03-17-2016 |
