摘要： The magnetic read write head has a read head and a write head, each having an end face exposed on an air bearing surface. The write head performs heat assist magnetic recording, and is provided with: a magnetic pole having an end face exposed on the air bearing surface; a waveguide extending toward the air bearing surface to propagate light; and a plasmon generator provided between the magnetic pole and the waveguide, and generating near-field light based on the light propagated through the waveguide to emit the generated near-field light from the air bearing surface. The waveguide is surrounded by a clad layer, and the magnetic pole is in contact with a heat sink having a heat conductivity higher than that of the clad layer. Although the near-field light causes temperature rise, heat energy from the plasmon generator to the magnetic pole is released through the heat sink.

摘要： A method for producing a thin film magnetic head including a magnetoresistive effect element (MR element) that has a magnetic sensor multi-layered film with a polygonal shape such that a vertex angle faces an air bearing surface (ABS) and a tip of the vertex angle is cut when the magnetic sensor multi-layered film is viewed from an X-Y plane that is parallel to a plane of a lower shield electrode layer includes a step for stopping a lapping process by using a measurement point in which a resistance value is steeply increased while the lapping face is gradually approaching the vertex angle of polygonal shape by lapping from the ABS side. Therefore, an excellent effect in which an ultra narrow track width that exceeds limits of photolithography technology can be securely and constantly formed is obtained.

The method includes steps of: forming a laminate structure including the waveguide; the plasmon generator, and the magnetic pole in order; performing a first polishing process to planarize an end surface of the laminate structure; performing a first etching process to remove impurity attached on the end surface of the laminate structure, and to allow the plasmon generator to be recessed from the waveguide and the magnetic pole, thereby forming a recessed region on the end surface of the laminate structure; forming a protection layer on the end surface of the laminate structure such that at least the recessed region is filled; and performing a second polishing process on the end surface of the laminate structure formed with the protection layer until the plasmon generator is exposed, thereby completing the air bearing surface.

摘要： Provided is a thermally-assisted magnetic recording head comprising a near-field-light-generating (NFL-generating) optical system with an improved light use efficiency. The head comprises a magnetic pole, a waveguide propagating a light for exciting surface plasmon, and a NF-optical device configured to emit NF-light from its end surface located adjacent to the magnetic pole end surface. The waveguide cross-section, taken by a plane perpendicular to a waveguide edge along elongated direction, has substantially a trapezoidal shape in which a longer side of opposed parallel sides is an edge of the cross-section on the NF-optical device side. This configuration enables a coupled portion of the NF-optical device which is coupled with the light to be placed in the effective distribution range of the light seeping from the waveguide. Consequently, there can be realized a sufficiently strong coupling between the light seeping from the waveguide and the NF-optical device.
