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 gimbaled flexure having a dual stage actuation structure. The flexure comprises a gimbal on which a motor is mounted. The motor comprises a first terminal, one or more layers of piezoelectric material, and a metal stiffener disposed directly on the first terminal. The stiffener comprises a layer of metal defining a majority of a top side of the motor. The first terminal can be gold sputtered on the piezoelectric material while the stiffener can be nickel plated on the gold. The stiffener can cause the motor, and the flexure on which it is mounted, to curl upon electrical activation of the motor.

摘要： The present disclosure relates to methods and a related systems and tools for dispensing an adhesive piece having damping qualities onto a component of a hard disk drive suspension. The adhesive piece can be commercially available layered strip sold as an adhesive layer having a first and a second liner adhered to each side. An exemplary method can cut an adhesive piece, separate the adhesive piece from a secondary liner, adhere the adhesive piece onto a component of a hard disk drive suspension, separate a primary liner from the adhesive piece, and dispose of the primary liner using a conventional gantry system. The method can be performed using a two-step operation of the gantry system.

摘要： Various embodiments concern a flexure comprising a base metal layer. The base metal layer can have a void between a first lateral side and a second lateral side. The flexure can further comprise a plurality of traces in an array. The plurality of traces can extend over the void and between the first and second lateral sides. The plurality of traces can comprise a pair of outer traces respectively located on lateral ends of the array and at least one inner trace between the pair of outer traces. The plurality of traces and the first and second lateral sides can be spaced relative to each other such that adjacent traces of the plurality of traces capacitively couple to each other and the pair of outer traces capacitively couple with each other through the first and second lateral sides.

摘要： Various embodiments concern a gimbaled flexure having a dual stage actuation structure. The flexure comprises a gimbal on which a motor is mounted. The motor comprises a first and second terminals and a plurality of actuator layers formed from a piezoelectric material. The plurality of actuator layers comprise serially stacked first, second, and third actuator layers. The plurality of actuator layers are respectively poled and connected to the first and second terminals such that both of the first and second actuator layers expand while the third actuator layer contracts in response to application of a signal across the first and second terminals. The differential motion of the plurality of layers in the motor cause the motor to curl about the contracting third actuator layer. The curling motion causes a portion of the flexure to preferentially curl.

摘要： Various embodiments concern a suspension assembly of a disk drive. The suspension assembly includes a load beam comprising a major planar area formed from a substrate. The load beam further comprises a window in the substrate, a dimple formed from the substrate, and a flange. The flange is a region of the major planar area that extends partially around the dimple but does not extend along an edge of the dimple. The edge of the dimple is adjacent to the window. The dimple is in contact with the flexure. A HAMR block or other element can extend through the window. The lack of a full flange can minimize the necessary clearance between the dimple and the HAMR block or other element and thereby allow the window to be enlarged to accommodate the HAMR block or other element.
摘要翻译：各种实施例涉及磁盘驱动器的悬架组件。悬架组件包括负载梁，该负载梁包括由基板形成的主平面区域。负载梁还包括在基板中的窗口，由基板形成的凹坑和凸缘。凸缘是主要平面区域的部分围绕凹坑延伸但不沿着凹坑的边缘延伸的区域。凹坑的边缘与窗口相邻。凹坑与挠曲件接触。 HAMR块或其他元素可以延伸通过窗口。缺少整个法兰可以最小化凹坑和HAMR块或其他元件之间的必要间隙，从而允许窗口被扩大以容纳HAMR块或其它元件。

摘要： Various embodiments concern a suspension having a DSA structure on a gimbaled flexure comprising a loadbeam having a load point dimple and a flexure attached to the loadbeam. The flexure comprising a metal layer having a pair of spring arms, a tongue located between the spring arms, and a pair of struts. The struts connect the pair of spring arms to the tongue. One of the struts is located distal of the other strut. The pair of struts has a midline centered between the pair of struts. The suspension further comprises a motor mounted on the flexure. Electrical activation of the motor bends the pair of struts to rotate the tongue about an axis of rotation. The axis of rotation is aligned with the dimple. The midline is offset distally or proximally with respect to the axis of rotation. The offset counters a mass in imbalance of the tongue.
