摘要： A near-field light generator plate 36 of the present invention is arranged to face a medium 10, and one portion 36b and other portion 36a in a medium-facing surface S thereof are made of their respective electroconductive materials different from each other. Since the one portion and the other portion in the medium-facing surface are made of the electroconductive materials different from each other, this medium-facing surface is formed by a surface removing step such as polishing or etching from the medium-facing surface side so that a difference between heights of the one portion and the other portion is readily made based on the difference of the materials.

摘要： A pair of domain control layers are disposed on both sides of the track width direction of the MR film so as to be separated from each other such that the MR film is held therebetween, and apply a longitudinal magnetic field to the MR film (free layer). The MR film is flanked by the domain control layers, each including a layer structure constituted by a base layer, a ferromagnetic layer, and a hard magnetic layer. The base layer causes the hard magnetic layer to have a magnetization direction aligning with an in-plane direction, so as to enhance the coercive force of the hard magnetic layer.

摘要： A thin-film magnetic head comprises a magnetoresistive film, a pair of magnetic domain control layers for applying a bias magnetic field to the magnetoresistive film, a pair of electrode layers for supplying a current to the magnetoresistive film, first and second shield layers for shielding the magnetoresistive film, a first insulating layer disposed between the magnetoresistive film and magnetic domain control layer and the first shield layer, and a second insulating layer disposed between the magnetoresistive film and electrode layer and the second shield layer. The shield layers have a distance therebetween shorter at a position where the electrode layer and magnetic domain control layer are laminated than that at a position where the magnetoresistive film is located. While the surface of the magnetic domain control layer on the first insulating layer side at the position where the electrode film and magnetic domain control layer are laminated is taken as a reference surface, the distance from the reference surface to the surface of the electrode layer on the second insulating layer side is set shorter than the distance from the reference surface to the surface of the magnetoresistive film on the second insulating layer side.

摘要： A method for manufacturing a thermally-assisted magnetic recording head is provided, in which a light source unit including a light source and a slider including an optical system are bonded. A unit substrate is made of a material transmitting light having a predetermined wavelength, and a unit adhesion material layer that contains Sn, Sn alloy, Pb alloy or Bi alloy is formed on the light source unit and/or the slider. The manufacturing method includes: aligning the light source unit and the slider in such a way that a light from the light source can enter the optical system and the unit adhesion material layer is sandwiched therebetween; and causing a light including the predetermined wavelength to enter the unit substrate to melt the unit adhesion material layer. The unit adhesion material layer melted by the light including the predetermined wavelength can ensure high alignment accuracy as well as higher bonding strength and less change with time.

摘要： Provided is a head gimbal assembly (HGA) in which the electrodes for a thermally-assisted magnetic recording head comprising a light source, a photodetector and a magnetic head element, can be reliably electrically connected to wiring members by solder ball bonding (SBB). The HGA comprises a suspension comprising: a base; a first wiring member for the light source and the photodetector, provided on a side of one surface of the base; and a second wiring member for the magnetic head element, provided on the same surface side. The first and second wiring members protrude from the base toward the head to be fixed. As a result, the end portions (connection pads) of the first and second wiring members can be located close to electrodes for light-source and photodetector and electrodes for magnetic head element, respectively. This arrangement enables the end portions of the first and second wiring members to be reliably electrically connected to the electrodes by SBB.
