PURPOSE:To provide a magnetic head which has stable performance in sliding with a magnetic recording medium and is highly resistant to environment and wear by using a substrate having rock salt type crystal structure and consisting essentially of composite oxide ZnxNi1-xO (O<X<=0.5) and forming a soft magnetic material as a magnetic core on such substrate. CONSTITUTION:Pure water is added to a powder mixture composed of NiO and MgO and the mixture is granulated. The granules are uniaxially molded under the pressure in a metallic mold. The molding is put into an SiC mold and is hot-pressed with alumina as a pressure medium. The sintered body obtd. in the above-mentioned manner is cut and ground to form the substrate 1 having 0.1mum surface smoothness Rmax. The magnetic head is manufactured of the substrate 1 and a soft magnetic amorphous alloy consisting essentially of Co.
