Abstract
The present invention provides a method for producing a magnetic head whose reproduction waveform has small distortions, and forming a hard magnetism layer for applying a bias magnetic field to a magnetoresistive element, which is a multilayer film including a fixed magnetic layer having magnetization fixed to a first direction and a free magnetic layer having an easy axis of magnetization that is directed to a second direction, is formed in an area including at least one of a front area in the first direction and a rear area in the first direction.
