ABSTRACT:
A magnetic head supporting structure includes a stationary base, a movable arm which has its base end pivoted to the base and a spring for biasing the movable arm thereby allowing a free end of the arm to be moved closer to or separated away from the base. The base is provided with a first magnetic head mounting section for mounting a first magnetic head and the arm is also provided with a second magnetic head mounting section for mounting a second magnetic head at its free end. The first magnetic head mounting section is provided with a support surface generally rectangular in shape for supporting thereon a gimbal spring having fixedly mounted thereon the first magnetic head and a deflection limiting surface defined inwardly of the support surface. The gimbal spring comes into contact with the deflection limiting surface when deflected beyond a predetermined amount thereby preventing the gimbal spring from deflecting excessively.
