Abstract
PURPOSE:To provide a magnetic head which can deal with a high-coercive force tape by using a ferrite material, of which the molar ratios of Fe2O3/MnO/ ZnO are in the compsn. range enclosed by specific 4 points in the compsn. diagram and the content of bivalent iron is >=60% of the excess total iron content in which Fe2O3 exceeds 50mol.%. CONSTITUTION:The magnetic head is constituted by using the magnetic core consisting of the ferrite material, the molar ratios of Fe2O3/MnO/ZnO are in the compsn. range within the rectangle enclosed by the four points 61/21/18, 64/18/18, 61/15/24, 58/18/24, respectively, in the compsn. diagram and the content of the bivalent iron is >=60% in the excess total iron content in which Fe2O3 exceeds 50mol.%. The high-magnetic head which has a high magnetic flux density, has high coercive force even in a high-frequency range of >=5MHz and can lower sliding noises at >=1.5m/sec relative speed with a magnetic recording medium and in a frequency range inclusive of >=7MHz recording and reproducing frequency.
