摘要： A first side shield has a first sidewall and a second sidewall. A second side shield has a third sidewall and a fourth sidewall. The distance between the first sidewall and the third sidewall decreases with increasing proximity to the top surface of a substrate. The second and fourth sidewalls are close to perpendicular to the top surface of the substrate. Each of the second and fourth sidewalls has an edge farthest from the top surface of the substrate, the edge being parallel to the medium facing surface. The main pole has a first, a second, a third and a fourth side surface. The first side surface is opposed to the first sidewall. A portion of the second side surface is opposed to the second sidewall. The third side surface is opposed to the third sidewall. A portion of the fourth side surface is opposed to the fourth sidewall.

摘要： A method of manufacturing a thermally-assisted magnetic recording head includes the steps of: forming a preliminary head section that has a surface to be polished and includes a magnetic pole, a waveguide, and a preliminary plasmon generator; causing a volumetric expansion of the preliminary plasmon generator with heat by introducing light into the core of the waveguide of the preliminary head section; and polishing the surface to be polished of the preliminary head section into a medium facing surface. The preliminary plasmon generator has an end face located in the surface to be polished. In the step of polishing the surface to be polished, the surface to be polished is subjected to polishing with the preliminary plasmon generator expanded in volume, whereby the end face of the preliminary plasmon generator is polished into the front end face, and the preliminary plasmon generator thereby becomes the plasmon generator.

摘要： A method fabricates a magnetic transducer. A sacrificial leading shield is provided on an etch stop layer. A nonmagnetic layer is provided on the sacrificial leading shield. A pole trench is formed in the nonmagnetic layer and on the sacrificial leading shield. A pole is formed. The pole has a bottom and a top wider than the bottom in a pole tip region. Part of the pole in the pole tip region is in the pole trench and at the ABS location. The sacrificial leading shield and part of the nonmagnetic layer adjacent to the pole are removed. An air bridge thus resides in place of the sacrificial leading shield between the portion of the pole and the etch stop layer. As least one shield layer is provided. The at least one shield layer substantially fills the air bridge and form a monolithic shield including a leading and side shields.
