ことを特徴とする薄膜磁気ヘツド。 A flat lower magnetic pole is provided on the substrate, a flat upper magnetic pole is provided on the lower magnetic pole so as to form a magnetic gap with the lower magnetic pole, and the tip sides of the upper magnetic pole and the lower magnetic pole are connected to the magnetic field. In a thin film magnetic head that is arranged with a gap to face the recording medium surface and performs magnetic recording, the upper magnetic pole and the lower magnetic pole have approximately the same width along the recording medium surface, and at least one of the upper magnetic pole and the lower magnetic pole The width along the recording medium surface of the surface of the magnetic pole on the side opposite to the magnetic gap is made longer than the same width of the surface of the magnetic pole on the opposite side to the magnetic gap, so that the side surface of this one magnetic pole is substantially perpendicular to the recording medium and adjacent to the magnetic gap. A thin film magnetic head characterized by a tilted head.
