Abstract
The side edge of the main magnetic pole layer is prevented from protruding in the track width direction even when a skew angle is generated by forming the main magnetic pole layer of the opposing face opposing the recording medium as an inverted trapezoid, thereby enabling the occurrence of side fringing to be prevented.
