摘要： According to one embodiment, a perpendicular magnetic recording head includes a shield having a groove and a main magnetic pole positioned in the groove of the shield. The groove includes a bottom side near a leading edge of the shield and inclined sides extending from the bottom side toward a trailing edge of the shield and from an ABS side of the head to a recessed side of the shield opposite the ABS. The shield is coupled to a non-magnetic layer at the recessed side, a cross-sectional area of the groove is less at a position nearer to the substrate than a position farther from the substrate, a cross-sectional area of the groove is less at a position nearer to the ABS side of the shield than a position farther from the ABS side of the shield, and a portion of the sides of the groove have curved surfaces.

摘要： According to one embodiment, a magnetic head for perpendicular recording includes a main pole, a first soft magnetic film disposed on a trailing side of the main pole, and a first nonmagnetic film interposed between the main pole and the first soft magnetic film. A thickness of the main pole is increased in a depth direction from an air bearing surface using an inclination, and a thickness of the first nonmagnetic film increases in the depth direction from the air bearing surface. In another embodiment, an angle from a horizontal plane of an upper surface of the first nonmagnetic film is greater than an angle from a horizontal plane of a lower surface of the first nonmagnetic film in contact with the main pole. Other heads, methods, and systems are described according to more embodiments.
