摘要： A heat-assisted magnetic recording head includes a magnetic pole, a waveguide that allows light to propagate therethrough, a near-field light generating element that generates near-field light based on the light propagating through the waveguide, a convergent lens, and a laser diode disposed above the waveguide. The convergent lens transmits light that is emitted from the laser diode, so that the light transmitted through the convergent lens is incident on the waveguide.

摘要： A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a core part. The return path section includes a yoke part magnetically connected to the write shield, and a coupling part located away from a medium facing surface and magnetically coupling the yoke part and the main pole to each other. The first coil is located on the front side in the direction of travel of a recording medium relative to the main pole and wound around the coupling part. The core part is located farther from the medium facing surface than is the coupling part, and is magnetically connected to the main pole. The second coil is located on the front side in the direction of travel of the recording medium relative to the main pole and wound around the core part.

摘要： A first side shield has a first sidewall and a second sidewall, and a second side shield has a third sidewall and a fourth sidewall. The first to fourth sidewalls have first to fourth edges, respectively, that are farthest from a top surface of a substrate. The distance between a rear end of the first edge and a rear end of the third edge in a track width direction is greater than the distance between a front end of the first edge and a front end of the third edge in the track width direction. The distance between the second edge and the fourth edge in the track width direction increases with increasing distance from the medium facing surface.

摘要： A thin-film magnetic head includes a coil, a magnetic path forming section, and an insulating film. The magnetic path forming section includes first and second magnetic material portions. The coil includes first and second coil elements located between the first and second magnetic material portions. The insulating film includes an underlying portion located under the first and second coil elements. In a method of manufacturing the thin-film magnetic head, the insulating film is formed to cover the first and second magnetic material portions, and then a seed layer is formed selectively on the underlying portion of the insulating film. The coil is formed by plating using the seed layer.
