Abstract
Various embodiments concern a suspension having a DSA structure on a gimbaled flexure. The suspension comprises a loadbeam and flexure attached thereto. The flexure comprises a pair of spring arms, a tongue located between the spring arms and structurally supported by the pair of spring arms, and a pair of struts. The struts are positioned respectively between the pair of spring arms and the tongue. The longitudinal axes of the struts are offset with respect to each other. The suspension further comprises a slider and a motor mounted on the flexure. The motor has a longitudinal axis that is parallel with the axes of the struts and perpendicular to a longitudinal axis of the loadbeam. Electrical activation of the motor bends the pair of struts to move the slider.
