Filed: 1992-05-28
Abstract: PURPOSE:To provide a thin film magnetic head having a magnetic layer deposited on an insulation layer in which exfoliation of lower magnetic layer, deformation of thin film head element, and occurrence of wiggle noise are prevented positively by forming a metal film between a substrate and the insulation layer. CONSTITUTION:When the temperature of a substrate 6 is set lower than a conventional level during filming operation, thermal energy is fed quickly and incessantly from a metal film 14 side to the initial growth layer of a lower magnetic layer 8 formed on the surface of an insulation layer 7 thus forming a lower magnetic layer 8 having magnetic characteristics suitable for a thin film magnetic head 13. Furthermore, since heating temperature of the substrate 6 can be set lower than a conventional level, residual stress in the lower magnetic layer 8 of the thin film head element 13 can be released remarkably as compared with a conventional one. Consequently, exfoliation of the magnetic layer 8 and deformation of the element 3 are prevented, fluctuation in the direction of anisotropic axis due to stress in the element 3 or reverse magnetostriction is suppressed, and wiggle noise is prevented.
