摘要： A method of manufacturing a thermally-assisted magnetic recording head includes: providing bar including, arranged in a first direction, a plurality of thermally-assisted magnetic recording head sections each including a waveguide, and a plurality of light source units each including a substrate with a light source mounted on a first surface of the substrate; bonding a second surface of the substrate to the bar with a bonding layer while allowing a light emitting position of the light source to be in opposition to the waveguide and allowing the first surface to be parallel to the first direction; and separating the bar for each of the thermally-assisted magnetic recording head sections. The substrate is bonded to the bar by radiating each laser beam from a dead angle direction where the first surface on which the light source units are provided is hidden from view.

摘要： An MR element in a CPP structure includes a spacer layer made of Cu, a magnetic pinned layer containing CoFe and a free layer containing CoFe that are laminated to sandwich the spacer layer. The free layer is located below the magnetic pinned layer. The free layer is oriented in a (001) crystal plane, the spacer layer is formed and oriented in a (001) crystal plane on the (001) crystal plane of the free layer. Therefore, in a low resistance area where an area resistivity (AR) of the MR element is, for example, lower than 0.3 Ω·μm2, an MR element that has a large variation of a resistance is obtained.

摘要： A thin film magnetic head includes a first through fourth free layers, a spacer layer, and a bias magnetic field application layer. The first and second free layers are magnetized in opposite directions of each other in the orthogonal direction to the ABS when the bias magnetic field is applied to the first and second free layers, and are exchange-coupled such that an angle between the magnetization direction of the bias magnetic field and the first free layer is acute and such that an angle between the magnetization direction of the bias magnetic field and the second free layer is acute. Similarly, the third and fourth layers have the same configuration.

摘要： A method of manufacturing a thermally-assisted magnetic write head is provided. 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.
