IPC: G11B5/127
Filed: 1990-03-20
Abstract: PURPOSE:To suppress the internal stresses generated in head substrates and magnetic metallic thin films with simple means by interposing an intermediate thin film consisting of partially stabilized zirconia formed by adding a stabilizer to zirconia between the head substrates and the magnetic metallic thin films. CONSTITUTION:The magnetic metallic thin films 7, 8 to constitute a gap spacer are inserted between a pair of the head substrates 3 to 6 consisting of alumina titanium carbide and are integrated by joining.
