ABSTRACT:
A head suspension for use in a rigid disk drive is provided having a diminished spring constant for minimizing the negative effects of load loss on head suspension performance without a diminished sway mode resonant frequency. The head suspension includes a load beam having an actuator mounting region, a rigid region, a flexure, and a spring region between the actuator mounting region and the rigid region. The spring region contains at least one torsion arm a component of which extends in a direction transverse to the length of the load beam. A displacement normal to the plane of the load beam of the head slider causes a twisting action in the torsion arm. This twisting action generates a force which opposes the normal displacement of the head slider. Preferably, the head suspension also includes a plurality of partial thickness tabs positioned in the spring region which are rigid in the plane of the load beam such that a force exerted at the head slider in the plane of the load beam is opposed by the rigidity of the partial thickness tabs. Thus, the tabs act to retain lateral rigidity of the load beam thereby maintaining a high sway mode resonant frequency.
