Abstract
The magnetic head of the present invention includes a magnetic body in the form of a flat plate, and a magnetic pole in the form of a pillar for applying a magnetic field to a recording medium, which is provided to rise on a portion of the magnetic body which is offset in one direction from a center of the magnetic body, and is provided with a coil around its outer periphery. Thus, the magnetic head has a core of a raised shape which is composed of the pillar-shaped magnetic pole being attached to the magnetic body in the form of a flat plate, making it possible to provide a heat capacity and a heat radiation area required for the core and the magnetic body, respectively, thus adapting to high frequencies. Further, because the magnetic pole is provided on a position which is offset in one direction from the center of the magnetic body, there will be no interference between the magnetic head and the cartridge or mechanical components even when the size of the core is increased due to the core of the raised shape. As a result, less restriction is imposed on a moving range of the magnetic head, thus using the entire recording area of the recording medium.
