PURPOSE:To establish the magnetic head having stable characteristics and long life, by eliminating the gap and providing the wear resistant material layer on the contact surface with the recording media and the head. CONSTITUTION:The wear resistant material layer 8 is provided at the head 7 of the magnetic head forming th core materials 4, 4 with bonding via the spacer 6 forming the magnetic gap 5, except for the gap 5. The said layer 8 is formed with sputter vapor deposition of about 100-500Angstrom of alumina, titania or silicon oxide, for example, at first and silicon carbide. It is desirable for tapered thickness gradually increased from the gap 5 to the both side surfaces 4a, 4b of the core material 4. |
