Abstract

PURPOSE:To provide a high-fineness magnetic head 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 63/27/10, 65/25/10, 63.5/20.5/16, 61.5/22.5/16, 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-fineness magnetic head which has a high magnetic flux density, is not deteriorated by saturation even with a high-coercive force magnetic recording medium and if, therefore, capable of making such recording and reproducing at >=1.5m/sec relative speed with the magnetic recording medium and the recording and reproducing frequencies in excess of 7MHz is thereby obtd.
