Abstract

PURPOSE:To improve high-frequency characteristics by using polycrystalline Mn-Zn ferrite added with 0.01-0.2wt.% ZrO2 to form oxide magnetic members which constitute magnetic core half bodies. CONSTITUTION:This magnetic head is constituted by welding and joining the magnetic core half bodies 5, 6, which are formed with thin 'SENDUST(R)' films 3, 4 of thin magnetic metallic films respectively to the oxide magnetic members 1, 2 at 45 deg. angle to working gap forming surfaces, by means of glasses 8, 9 and forming the working gap 7 to the joint surfaces of the thin 'SENDUST(R)' films 3, 4. The oxide magnetic members 1, 2 are formed of the polycrystalline Mn-Zn ferrite added with 0.01-0.2wt.% ZrO2. The high-frequency characteristics are thereby improved and the dislodgment of the crystal grains generated on the tape sliding surfaces of the oxide magnetic members 1, 2 through a stage for forming the thin magnetic metallic films 3, 4 and a stage for polishing the tape sliding surfaces is greatly decreased.
