IPC: G11B5/31
Filed: 1985-09-27
Abstract: PURPOSE:To improve the recording and reproducing characteristics and to form the magnetic head by executing the thermal processing, etc., in the magnetic field and making the easy-to-magnetize direction of the magnetic thin film into the necessary direction. CONSTITUTION:A ring type magnetic head is composed of a substrate 1 connected through a gap material 11 and a magnetic thin film 2, a protective film 8, etc., formed by the evaporation, etc., on it. When the thin film 2 is thermally processed in the magnetic field by the magnetic pole inserted into a winding window 9 of the head and the magnetic field of the head outer circumferential part, an easy-to-magnetize direction 7' of the thin film 2 comes to be radiation- shaped toward the external part in the direction almost perpendicular to the magnetic path direction 6. Thus, the high frequency permeability in the magnetic path direction comes to be high, the recording reproducing characteristic of the head is improved even to the high frequency and the magnetic head is easily formed by the simple processing. Even when the magnetic anisotropy is given to the thin film 2 by the magnetic field only, the same operation is executed.
