  • Patent number: 5063464
    Abstract: The present invention relates to a magnetic head suspension in a magnetic disk storage with a record carrier moved relative to the magnetic head and separated therefrom by an air cushion. The head suspension assembly with suspension arm 3, flexure 19 and slider 30 is fixed to an arm portion 1 at a point where arm portion 1 is provided with a ramp 2. This ramp eliminates prebiasing the suspension arm 3. The free end of the suspension arm 3 is provided with a raised portion 5. The elements 25, 26 fixing the tongue 27 to the flexure 19, in particular the bracket 25 with the attached tongue 27 on which the slider 30 is arranged, are substantially recessed in the raised portion 5 of the suspension arm 3. As a result, there is a noticeably reduced overall height.
