摘要： A head gimbal assembly has a suspension configured to extend along a surface of a recording medium and to bend and deform in a thickness direction of the recording medium. A slider is provided on a front end side of the suspension so as to confront the surface of the recording medium. A support section supports the slider such that the slider can pivot about two axes parallel to the surface of the recording medium and perpendicular to each other. An optical waveguide is connected to the slider and is configured to introduce a light flux into the slider. A near-field light generating element generates near-field light from the optical flux and causes the near-field light to record information on the recording medium. A positioning section is mounted between the support section and the slider for positioning the optical waveguide relative to the slider.

摘要： A metal film is included which is placed between a core and a cladding, propagates a laser beam along an interface between the core and the cladding, and generates a near-field light from the laser beam. The metal film has a base portion placed on one side surface of the core along a propagation direction of the laser beam facing from one end side toward the other end side, and an extending portion extended from the other end side of the base portion to the other end side in the propagation direction rather than the core. The other end side of the extending portion is exposed to the outside, and is formed with a top portion projected toward the core side when viewed from the propagation direction.

摘要： A method of manufacturing a near-field optical head. A first projection shaped in a quadrangular pyramid is formed on a surface of a substrate for providing a near-field optical element of the near-field optical head. A second projection shaped in a frustum of quadrangular pyramid is formed on the surface of the substrate for providing an air bearing surface of the near-field optical head. A metal film is formed on at least one surface of the first projection and the metal film is connected with a resistance meter through a conduction wiring for detecting an electrical resistance of the metal film. The first and second projections and the metal film are polished while the resistance meter detects an electrical resistance of the metal film and until the detected electrical resistance reaches a predetermined value such that a top surface of the first projection has a specified size and becomes flush with a surface of the second projection providing the air bearing surface.

摘要： An information recording and reproduction apparatus has a magnetic recording medium, a light source that outputs a light beam to heat the medium, and a near-field light head confronting a surface of the medium. An optical waveguide introduces a light beam from the light source into the near-field light head to generate near-field light. A control section supplies a current to a recording element of the near-field light head for generating a recording magnetic field in a direction of the medium. A photoelectric composite wiring line has the optical waveguide and at least one electric wiring line integral with the optical waveguide and electrically connecting the near-field light head to the control section. The optical waveguide and the electric wiring line branch off from a distal side of the photoelectric composite wiring line so as to connect to the near-field light head.
