摘要： Gimbal designs are provided that minimize adverse dynamic performance of a HDD suspension, particularly subsequent to head-disk-interface (HDI) interactions. The improvement of operational performance can be seen in graphical representations of the vibrational modes of a gimbal mounted slider subsequent to such HDI interactions. Each gimbal design includes a ramp limiter formed as two separated arms connected by one or two transverse bars and a routing of conducting traces that relieves stress and minimally contacts these bars.

摘要： A loadbeam is locally stiffened by either, 1. the addition of strategically placed extra material to the loadbeam, 2. not removing material during the etching process to form the loadbeam, or 3. special forming, by crimping or bending, at specific sites on the beam. The use of local stiffening, when placed about the loadbeam dimple or between the dimple and flexure attachment points, with or without additional damping, can significantly improve the dynamical response of the loadbeam and eliminate vibrational modes of a slider mounted on the loadbeam during HDI interactions with disk surface asperities during disk drive operation.
摘要翻译：负载梁由以下两者局部加强：1.向负载梁添加策略性放置的额外材料，2.在蚀刻过程中不去除材料以形成载荷梁，或3.通过卷曲或弯曲在特定位置上进行特殊成形梁。使用局部加强，当放置在负载梁凹坑下方，或者在凹坑和挠曲附着点之间，在有或没有附加阻尼的情况下，可以显着改善载荷梁的动力响应，并消除在HDI相互作用期间安装在载荷梁上的滑块的振动模式在磁盘驱动器操作期间具有磁盘表面粗糙度。

摘要： A system and method for testing the stroke and frequency response of a micro-actuator is disclosed. A dynamic parameter tester writes two concentric tracks on a noise free portion of a magnetic storage medium. A magnetic read/write head and a micro-actuator is positioned between the two concentric tracks. An initial oscillating voltage is applied at a first frequency to the micro-actuator while reading back a signal from the two concentric tracks. A stroke characteristic of the micro-actuator is calculated based in part on the read-back signal. The initial oscillating voltage is determined from previous tests. The first stroke characteristic of the micro-actuator is based on a time-averaged amplitude of the first signal. The two concentric tracks are written at a pre-determined pitch.

摘要： A flexure mounted slider and its method of fabrication is described, wherein the slider is affixed to a pair of highly compliant, transverse (to the longitudinal axis of a load beam) crossbars whose common axis passes directly above the center of percussion of the slider. The location of the center of percussion of the slider relative to the flexure eliminates translational motion of the slider during HDI events, but not twisting motion in a pitch direction during normal operation, and thereby minimizes the transfer of kinetic energy between the slider and the flexure during HDI events with a hard disk. The high compliance of the flexure crossbars to twists in a pitch direction, as well as the compliance of the outriggers to bending, allows the slider to pass over irregularities in the disk during normal operations.
摘要翻译：描述了一种弯曲安装的滑块及其制造方法，其中滑块固定在一对高度柔顺的横向（相对于负载梁的纵向轴线）的横梁上，其公共轴线直接穿过滑块的冲击中心。滑块相对于弯曲部的冲击中心的位置消除了HDI事件期间滑块的平移运动，而在正常操作期间不会在俯仰方向上扭转运动，从而使滑块和挠曲件之间的动能传递最小化在HDI事件与硬盘。弯曲横梁在俯仰方向上的高度柔顺性以及外伸支架对弯曲的顺应性允许滑块在正常操作期间经过盘中的不规则。
