摘要： A near-field light generator includes: a waveguide; a clad layer having a penetrating opening and disposed on the waveguide; a plasmon generator accommodated in the opening; and a dielectric film interposed between the plasmon generator and each of the waveguide and the clad layer. In a method of manufacturing the near-field light generator, an initial clad layer is initially formed on the waveguide, and then the initial clad layer is taper-etched by RIE to form a recess that does not reach the top surface of the waveguide. Subsequently, the recess is etched by wet etching until the top surface of the waveguide is exposed in part. Next, the dielectric film is formed in the opening, and the plasmon generator is formed on the dielectric film.

摘要： A top surface of a pole layer of a magnetic head includes: a first portion having a first edge located in a medium facing surface and a second edge opposite thereto; and a second portion located farther from the medium facing surface than the first portion and connected to the first portion at the second edge. The distance from a substrate to an arbitrary point on the first portion increases with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination of the first portion taken at the arbitrary point with respect to a direction perpendicular to the medium facing surface increases stepwise or continuously with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination taken at the first edge is greater than zero degree. The second portion extends in a direction substantially perpendicular to the medium facing surface.

摘要： A magnetic head includes: a pole layer including a track width defining portion and a wide portion; and an encasing layer disposed on a bottom forming layer and having a groove that accommodates the pole layer. The groove includes a first portion for accommodating at least part of the track width defining portion, and a second portion for accommodating at least part of the wide portion. A manufacturing method for the magnetic head includes: the step of etching a nonmagnetic layer that will become the encasing layer later, such that an initial groove including the first portion is formed in the nonmagnetic layer; the step of forming an initial groove mask covering the first portion; and a second etching step for etching the nonmagnetic layer so as to complete the groove. When the second etching step starts, a portion of the top surface of the bottom forming layer located in a region in which the second portion is to be formed is covered with the nonmagnetic layer or the initial groove mask.
