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 system and method for dynamically controlling the position of a hard drive head is disclosed. The system includes a hard drive slider comprising a first substrate, a second substrate coupled to the first substrate wherein the second substrate comprises a plurality of flexures wherein at least one of the flexures is responsive to an applied current, the flexure expanding in response to the current; and a third substrate coupled to the second substrate comprising vias to provide said current to the flexure. Embodiments of the invention can be used in contact and non contact recording situations and for absorbing mechanical vibrations.

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： Embodiments of the present invention pertain to a disk drive coupling apparatus for rigidly coupling a disk drive to a chassis of a computer. In one embodiment, the disk drive coupling apparatus includes a disk drive to chassis coupler and a disk drive to chassis coupler engaging mechanism. One end of the disk drive to chassis coupler can be coupled to the chassis of the computer. The disk drive to chassis coupler engaging mechanism is capable of causing the other end of the disk drive to chassis coupler to apply pressure to the disk drive, thus, the disk drive can be rigidly coupled to the chassis.

摘要： A method for adjusting the pitch and roll static torques (PST and RST) on a slider in a disk drive head-suspension assembly (HSA) during manufacturing assures that each HSA is manufactured with acceptable PST and RST values. The method includes measuring each slider's pitch and roll static attitudes (PSA and RSA) and determining each HSA's pitch and roll torsional stiffnesses. These values are then used to calculate the required amount of adjustment to PSA and RSA to achieve the desired values of PST and RST for each HSA. The suspension is then adjusted, such as by heating the flexure with a laser.
