摘要： A main magnetic pole member and an auxiliary magnetic pole member of a perpendicular magnetic recording head are disposed such that they are opposed to each other with a recording medium for recording a signal thereon (i.e., a magnetic tape) interposed therebetween. In the central portion of a holder of the main magnetic pole member, a magnetic pole film is embedded such that its upper end edge is exposed on a sliding contact surface of the holder. The magnetic tape is brought into sliding contact with the magnetic pole film. A pair of electrodes are embedded in such a manner as to sandwich an upper end portion of the magnetic pole film within the holder, and at positions spaced by a suitable distance from such upper end portion of the magnetic pole film. The auxiliary magnetic pole member causes the generation of a uniform magnetic flux directed from the auxiliary magnetic pole member toward the magnetic pole film. The magnetic pole film is formed of a magnetic material which has its permeability varied upon application thereto of an electric field. When a voltage is applied to the electrodes in accordance with the signal, an electric field is formed in the magnetic pole film to increase or decrease the permeability thereof, thereby causing an increase or decrease in density of the magnetic flux in the vicinity of the magnetic pole film. Thus, the magnetization of the magnetic tape is inverted or noninverted with the result that perpendicular magnetic recording of the signal is effected.
