  • Patent number: 4796132
    Abstract: Conductor film terminals of a thin film magnetic head are composed of an Au film while lead terminals of a flexible printed circuit board are covered with an Au layer, so that both of these terminals can be bonded by low temperature ultrasonic bonding directly between Au and Au. The reverse surface of the lead terminals of the flexible printed circuit board is bonded and fixed to a flexible polymer resin cover film so that the dimensional accuracy of the bonded terminal portion can be improved.

  • Patent number: 4695909
    Abstract: A magnetic head for recording and reproducing information on and from a flexible magnetic recording tape. The active face of tape supporting protrusions formed in the magnetic head is so configured that the contacting area between the supporting protrusion and the recording tape is smaller at both end portions of the protrusion than an intermediate portion thereof as viewed in the direction widthwise of the recording tape, whereby improved contacting state and floating state between the magnetic head and the recording tape can be assured over the whole width of the flexible recording tape.
