A magnetic head includes an encasing layer made of a nonmagnetic material
and having a groove that opens in the top surface; a nonmagnetic metal
layer made of a nonmagnetic metal material, disposed on the top surface
of the encasing layer, and having a penetrating opening that is
contiguous to the groove; and a pole layer made of a magnetic metal
material and encased in the groove of the encasing layer and in the
opening of the nonmagnetic metal layer. The pole layer has an end face
located in a medium facing surface, the end face having a first portion
and a second portion that is located farther from a substrate than the
first portion and connected to the first portion. The first portion has a
width that decreases as the distance from the substrate decreases. The
second portion has a uniform width that defines the track width. In the
medium facing surface, the nonmagnetic metal layer exists on both sides
of the second portion, the sides being opposed to each other in the
direction of track width.
