Patent ID: 7990655

Claim:
A perpendicular magnetic recording head comprising a main magnetic pole layer including a magnetic pole part exposed at a surface opposing a recording medium, a return yoke layer laminated with a predetermined distance on the main magnetic pole layer and magnetically coupled to the main magnetic pole layer on the deeper side of the medium-opposing surface in a height direction, and a nonmagnetic material layer covering the main magnetic pole layer, the magnetic pole part exhibiting a trapezoidal form narrower at a leading edge than at a trailing edge on the return yoke layer side when seen from the medium-opposing surface; wherein a magnetic shield layer made of a soft magnetic material is provided on the leading edge side of the magnetic pole part of the main magnetic pole layer while interposing the nonmagnetic material layer therebetween; wherein the magnetic shield layer has a pair of side shield parts separated from each other at the leading edge of the magnetic pole part so as to oppose both side faces in a track width direction of the magnetic pole part, and a bottom shield part magnetically connected to the pair of side shield parts and positioned below a leading edge of the magnetic pole part; and wherein, in the pair of side shield parts, end faces opposing both side faces in the track width direction of the magnetic pole part are positioned between a side face position in the track width direction on a trailing edge surface of the magnetic pole part and a side face position in the track width direction on a leading edge surface of the magnetic pole part.
