PURPOSE:To obtain a highly reliable thin film magnetic head which makes an excellent tape touch and has proper stress in a magnetic layer by using a glass thin film as the adhesive layer between a nonmagnetic substrate and the magnetic layer and adhering the nonmagnetic substrate and magnetic layer together tightly. CONSTITUTION:The thin film magnetic head consists of the laminate of the nonmagnetic substrate 1', magnetic layer 2, and nonmagnetic substrate 1, and a head gap 4 having specific width in the thickness direction of the magnetic layer 2 is formed. The magnetic layer 2 is formed on the nonmagnetic substrate 1 by sputtering and adhered to the nonmagnetic substrate 1' by using the glass thin film 3 with low melting point as an adhesive. The glass thin film 3 has excellent coupling with the nonmagnetic substrate 1' and magnetic layer 3, and causes no trouble to a run of a tape even when contacting the tape; and the film thickness is specified in its manufacture process to generate specific stress in the magnetic layer 3, obtaining specific magnetic characteristics. |
