Particularly, there is provided a perpendicular magnetic recording head
capable of suppressing PTP and obtaining a stabilized recording ability
by improving the shape of the opposed surface of a return yoke layer and
a method of manufacturing the same. The shape of the return yoke layer on
the opposed surface includes a downside formed linearly parallel to a
track width direction (X direction shown in the drawing), a center
portion where a protrusion portion having a maximum width T1 larger than
a track width Tw by protruding upwardly is formed in a position opposed
to a main magnetic pole layer in a film thickness direction (Z direction
shown in the drawing), and opposed end portions, having a film thickness
smaller than the center portion, that extend on the opposite sides in the
track width direction of the center portion. As a result, it is possible
to properly obtain both effects such as the improvement of the recording
ability and the suppressing of PTP generation.
