摘要： A thermally-assisted magnetic recording head includes a main pole, a waveguide, and a plasmon generator. The main pole has a front end face including first and second ends that are opposite in a track width direction. An arbitrary cross section of the main pole that passes through an arbitrary point on the front end face and is perpendicular to a medium facing surface and to the track width direction has a length in a direction perpendicular to the medium facing surface. When the arbitrary point on the front end face is located at a center of the front end face in the track width direction, the length of the arbitrary cross section is smaller than that when the arbitrary point is located at the first end and that when the arbitrary point is located at the second end.

摘要： A magnetic memory element includes a pair of electrodes, a junction layer, at least one carbon nanotube, and at least one nanowire. The at least one nanowire is made of a ferromagnetic material and extends through a hole of each the at least one carbon nanotube with both ends being electrically connected to the pair of electrodes, respectively. The junction layer is made of a non-magnetic material and disposed between one of the pair of electrodes and one end of each the at least one nanowire. The one of the pair of electrodes is made of a ferromagnetic material. Magnetization of the at least one nanowire is reversed by spin injection performed through the junction layer with the one of the pair of electrodes. When a DC bias current and a detection current having a frequency coinciding with a magnetic resonance frequency of the nanowire are applied in a superimposed manner, between the electrodes, within a range not reaching a critical current density of the magnetization reversal, the pair of electrodes have a voltage corresponding to a magnetization direction of the nanowire.

摘要： A pole layer incorporates a track width defining portion and a wide portion. The track width defining portion has an end face that is located in the medium facing surface and that defines the track width. The maximum width of the wide portion is greater than the track width and equal to or greater than the length of the wide portion taken in the direction orthogonal to the medium facing surface. When the coil is generating no magnetic field, in the end face of the track width defining portion, there exist first and second regions in which the directions of components of magnetization orthogonal to the medium facing surface are opposite.

摘要： The invention is devised to provide a method of manufacturing a thin film magnetic head including a magnetoresistive element having higher reading performance. In manufacturing the thin film magnetic head, after forming an MR element 15, a pair of magnetic domain controlling layers 16 are formed by stacking a buffer layer 161, a magnetic bias layer 162 and a cap layer 163 in this order on both sides, in a track-width direction, of the MR element 15 via an insulating layer 14 respectively. Then, a cap layer 17 is formed so as to cover the upper surface of the MR element 15 and connect the pair of cap-layers 163. After that, a gap adjustment layer 18 and a top shielding layer 19 are formed in order so as to cover the pair of cap layers 163 and the cap layer 17, thereby a read head section 10 is completed. In this manner, the upper surface of the magnetic bias layer 162 is in contact only with the cap-layer 17 and the cap-layer 163, which are made of a material excellent in crystal lattice compatibility with the magnetic bias layer 162. As a result, the coercive force of the magnetic bias layer 162 can be increased. What is more, roughness of the undersurface of the top shielding layer 19 can be improved because of the presence of the cap layer 17.
