Abstract
A top surface of a pole layer of a magnetic head includes: a first portion having a first edge located in a medium facing surface and a second edge opposite thereto; and a second portion located farther from the medium facing surface than the first portion and connected to the first portion at the second edge. The distance from a substrate to an arbitrary point on the first portion increases with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination of the first portion taken at the arbitrary point with respect to a direction perpendicular to the medium facing surface increases stepwise or continuously with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination taken at the first edge is greater than zero degree. The second portion extends in a direction substantially perpendicular to the medium facing surface.
