ABSTRACT:
A thin film vertical magnetization transducer head comprises an auxiliary magnetic pole of larger thickness and a main magnetic pole of smaller thickness having a pole face opposed to and spaced from the pole face of the auxiliary pole to define an air gap therebetween and to form a thin-film magnetic core with the auxiliary magnetic pole. A thin-film nonmagnetic structure supports the thin-film magnetic core so that the main pole is substantially centered with respect to the thickness of the auxiliary pole. The nonmagnetic structure is formed with a passage extending to the air gap to allow the magnetic recording medium to pass through the air gap in the direction of the thickness of the core. A coil structure is provided insulatively surrounding the auxiliary magnetic pole for generating a magnetic field across the pole faces.
