发明名称 Magnetic head and method of manufacturing the same
摘要 Embodiments of the present invention help to suppress broadening of a write field of a main pole of a perpendicular recording head and realize high-quality write operation. According to one embodiment, a main pole of a write head extends to an air bearing surface or a medium-facing surface and has an inverted trapezoid in cross-section. First soft magnetic films called side shields are separately disposed through a nonmagnetic film on both sides of the main pole. The air bearing surface side end of the first soft magnetic film is provided to recede from the air bearing surface. The first soft magnetic film and the main pole are formed in the same layer. A second soft magnetic film called a trailing shield is provided above the main pole on the air bearing surface side via a nonmagnetic film.
