Abstract

According to one embodiment, magnetic reproducing element for detecting a magnetic field from a magnetic recording medium comprises a sensor film including a perpendicular magnetization film having a magnetization easy axis in a direction perpendicular to a film plane, wherein magnetization in the sensor film tilts upward or downward in an element height direction from the magnetization easy axis while no magnetic field is applied from the magnetic recording medium, and change in anomalous Hall voltage generated in the sensor film is detected, thereby allowing the magnetic field applied from the magnetic recording medium to be detected. Other magnetic reproducing elements and magnetic heads employing magnetic reproducing elements are described as well.
