Abstract
A magnetic head of the present invention is to switch a direction of magnetic fields applied to a heated portion in a recording region in accordance with recording information. The magnetic head is composed of a single magnetic pole in a pillar shape and a coil. The magnetic pole is provided on a magnetic base, with one end surface of the magnetic pole brought into contact with the magnetic base. The coil, wound around the magnetic pole, is provided for generating the foregoing magnetic fields. The foregoing arrangement enables suppression of heat generation at the magnetic head, thereby allowing the recording frequency to be set higher, as well as improving the recording rate.
