摘要： Various embodiments concern a dual stage actuation flexure. The dual stage actuation flexure comprises a flexure having a gimbal. The gimbal comprising a pair of spring arms, a tongue between the spring arms, and a pair of linkages respectively connecting the pair of spring arms to the tongue. The dual stage actuation flexure further comprises a pair of motors mounted on the gimbal and a pair of stiffeners respectively mounted on the motors. The dual stage actuation flexure further comprises a slider mounting. Electrical activation of the motors bends the pair of linkages to move the slider mounting about a tracking axis while the stiffeners limit the degree of bending of the motors during the electrical activation.

摘要： 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.

摘要： Various embodiments concern a head suspension system having a load beam. The lead beam comprises a metal base having a proximal portion and a distal portion. Two opposing rails extend along the proximal and distal portions. The load beam has a void in the metal base separating the proximal portion from the distal portion, the void extending between the rails. A pair of microactuators is coupled to each of the proximal portion and the distal portion such that each microactuator extends across the void. The microactuators bend the rails to move the distal portion along a X-Y plane relative to the proximal portion. Additionally, the rails stiffen the load beam to resist movement between the first portion and the second portion along a Z-axis.
