摘要： A magnetic head includes a side shield layer and an encasing layer. The side shield layer has a first end face located in the medium facing surface, a second end face opposite to the first end face, and a first groove accommodating a portion of a pole layer. The first end face includes two portions located on both sides of an end face of the pole layer that are opposite to each other in a track width direction. The encasing layer is formed of a nonmagnetic material and disposed on a side of the side shield layer opposite to a medium facing surface. The encasing layer has a front end face touching the second end face of the side shield layer, and a second groove accommodating another portion of the pole layer. The distance from the medium facing surface to an arbitrary point on the second end face of the side shield layer decreases with decreasing distance from the arbitrary point to the top surface of a substrate.

摘要： A near-field light generating element has an outer surface including first and second inclined surfaces and an edge part that connects the first and second inclined surfaces to each other. In a method of manufacturing the near-field light generating element, a polishing stopper layer is initially formed on a metal layer, and the polishing stopper layer and the metal layer are etched so that the metal layer is provided with the first inclined surface. Next, a coating layer is formed to cover the metal layer and the polishing stopper layer. The coating layer is made of a non-metallic inorganic material that has an etching rate lower than that of the metal layer in a second etching step to be performed later. Next, the coating layer is polished until the polishing stopper layer is exposed. Next, the second etching step is performed to etch the polishing stopper layer and the metal layer using the coating layer as the etching mask. This provides the metal layer with the second inclined surface and the edge part, and thereby makes the metal layer into the near-field light generating element.

摘要： A heat-assisted magnetic recording head includes a magnetic pole, a waveguide, a near-field light generating element, and a substrate on which they are stacked. The near-field light generating element and the waveguide are disposed farther from the top surface of the substrate than is the magnetic pole. The near-field light generating element has an outer surface including: a first end face located in the medium facing surface; a second end face farther from the medium facing surface; and a coupling portion coupling the first and second end faces to each other. The first end face includes a near-field light generating part. The waveguide has an outer surface including an opposed portion opposed to a part of the coupling portion. The head further includes a mirror that reflects light emitted from a light source disposed above the waveguide, so as to let the light travel through the waveguide toward the medium facing surface.
