ABSTRACT:
Magnetic head for use in vertical recording has a main magnetic pole of a thin film of soft magnetic material enclosed between two protective blocks together constituting the body of the magnetic head. One protective block includes a magnetic part and a non-magnetic part, the latter extending from the boundary surface of the two parts up to the contact surface between the main pole and a magnetic recording medium. A channel provided at the boundary surface in the magnetic part of the protective block causes a part constituting an auxiliary magnetic pole and adjoining the main magnetic pole to be separated from a part constituting the return path for the magnetic flux from the main pole, a winding embracing the main pole and the auxiliary pole being wound through the channel. The other protective block consists entirely of a non-magnetic material and has a polished surface facing the one protective block, while the main pole is provided on the polished surface.
