Abstract
A magnetic head disposed in a slider arranged with an interval with respect to a magnetic disk includes a sensor that is positioned in a stepped-back position from an air bearing surface facing the magnetic disk, an insulating film that is positioned on the air bearing surface and that covers the sensor; a pair of lead films, the lead films being electrically connected to the sensor such that at least portions of the lead films are exposed on the air bearing surface, and being configured to transfer a temperature change of the air bearing surface to the sensor.
