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.

摘要翻译： 提供了云台设计，可以最大程度地降低HDD悬架的不利动态性能，特别是在磁头 - 磁盘接口（HDI）交互之后。 在这种HDI相互作用之后，万向节安装的滑块的振动模式的图形表示可以看出操作性能的改善。 每个万向节设计包括斜坡限制器，其形成为通过一个或两个横向杆连接的两个分离的臂，以及减轻应力并最小程度地接触这些杆的导电迹线的布线。

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： In a balanced head gimbal assembly for improved seeking performance, a slider having a magnetic head with a set of read elements to read data and a set of write elements to write data, an air-bearing surface, and a non-air-bearing surface is coupled to a suspension. The suspension includes a loadbeam, a flexure, and a balancing weight. The loadbeam is coupled to an actuator arm. The flexure, coupled to the loadbeam, has a window through which a dimple, coupled to the loadbeam, contacts a dimple contact point. The balancing weight, coupled to the flexure, has a configuration which permits alignment of a center of mass of the head gimbal assembly with the dimple contact point.
