摘要： A rotary actuator motor is provided including a stationary coil section and a rotating magnet. The magnet is incorporated with the pivot bearing assembly, and the coil section is aligned with the magnet along an axis of rotation of the actuator. The magnet fully encircles the axis of rotation. The coil comprises one or more closed loops of electrically conductive material. The motor in this arrangement maintains a much smaller profile in comparison to a traditional voice coil motor that is mounted to a yoke extending away from the axis of rotation of the actuator.

摘要： The invention includes sliders provided with indented surfaces, reducing the roll center for head gimbal assemblies below the effective thickness of the slider. Head gimbal assemblies built with these sliders may reduce off-track displacements induced by disk vibration. The load beam gimbal may contact the indented surface, creating a slider roll center less than the slider thickness. Alternatively, the sliders may include a slider contact cover interfacing to the load beam forming the gimbal. The slider contact covers may couple with the slider through an indented surface located closer than the slider thickness. These may have a negative slider roll center. The invention includes actuator arms, actuator assemblies, and hard disk drives including these head gimbal assemblies. The invention includes making the invention's sliders, head gimbal assemblies, actuator arms, actuator assemblies, and hard disk drives. The invention includes the products of these processes.
摘要翻译：本发明包括设置有凹入表面的滑块，将头万向架组件的滚动中心减小到低于滑块的有效厚度。使用这些滑块构建的头万向节组件可能会减少由磁盘振动引起的离轨位移。负载梁万向架可以接触凹槽表面，产生小于滑块厚度的滑块中心。或者，滑块可以包括与形成万向节的负载梁接合的滑块接触盖。滑块接触盖可以通过位于比滑块厚度更靠近的凹入表面与滑块相连。这些可能具有负滑块滚动中心。本发明包括致动器臂，致动器组件和包括这些头万向架组件的硬盘驱动器。本发明包括制造本发明的滑块，头万向架组件，致动器臂，致动器组件和硬盘驱动器。本发明包括这些方法的产物。

摘要： A method for centering the disk of a disk stack assembly. The method includes the step of applying a torque to the disk stack and spinning the disks. Both the torque and the spinning speed are less than normal operating values. A series of radial forces may then be applied to the disk stack. The series of forces will cause the rotating disks to self center. The rotating disks are eventually spun down and a full torque is applied to the disk stack to secure the disks.
摘要翻译：一种用于对准盘堆组件的盘的方法。该方法包括向磁盘堆栈施加扭矩并旋转磁盘的步骤。扭矩和旋转速度均小于正常工作值。然后可以将一系列径向力施加到盘堆。一系列力将使旋转盘自我中心。旋转盘最终被旋转，并且将完整的扭矩施加到盘堆以固定盘。

摘要： What is disclosed is a method and apparatus for writing servo information on disks to be used in a hard disk drive assembly. In one embodiment, servo information is pre-written onto a disk using an offline servo track writer which employs a fluid dynamic bearing spindle to rotate the disk(s) during read/write operations. In another embodiment, servo information is written onto a disk by a method of track following on a reference disk using an offline servo track writer.
摘要翻译：所公开的是将伺服信息写入要在硬盘驱动器组件中使用的盘上的方法和装置。在一个实施例中，使用离线伺服轨迹写入器将伺服信息预写入盘上，所述离线伺服记录器在读/写操作期间使用流体动态轴承主轴来旋转盘。在另一个实施例中，通过使用离线伺服轨迹写入器的参考盘上的跟踪方法将伺服信息写入磁盘。
