    摘要： The present invention includes four sections or partitions: two thrust bearings which are formed by the sides of a grooved thrust plate and corresponding countersurfaces, the thrust bearings designed to cause fluid flow in a single direction up around the rotating thrust plate and upward along the surface of a rotating journal, and two journal bearings formed side-by-side on the journal formed between a rotating shaft and a bushing with multiple spiral-grooved sections being formed on the rotating shaft or in the stationary bushing. The two journal bearings are separated by a circumferential groove in the shaft which is connected by a radial bore to a hollow reservoir in the shaft for providing fluid to the journal bearing and the thrust bearing. By providing this bore and a second bore located near to the thrust bearing, the boundary conditions for the combined journal bearings and thrust bearings are fixed and a stable rotating shaft is achieved.

    摘要： A hydrodynamic bearing incorporates a flexible membrane at one end of the fluid gap in the hydrodynamic bearing. If voids exist in the fluid, and if changes in the size of these voids or bubbles occur with changes in temperature or pressure in which the disc drive is being used, then the volume of the fluid will change, and increase relative to the change in size of the volume of the surrounding physical part. The flexible membrane will yield to the increased pressure of the increasing volume of the fluid. The membrane essentially acts as a spring whose spring force is overcome by the pressure created by or accompanying a increase in volume of the fluid. As this happens, the spring force of the membrane is overcome, the membrane relaxes and forms a bladder, effectively increasing the volume in which the lubricating fluid is contained, and preventing its escape or being forced out of the inner region of the bearing. In this way, the fluid remains in the bearing and will not enter the surrounding atmosphere, nor will it be lost from the journal bearing region so that the hydrodynamic bearing is not as effective, when the temperature decreases or the pressure drops.

    摘要翻译： 流体动力轴承在流体动力轴承中的流体间隙的一端处包含柔性膜。 如果流体中存在空隙，并且如果在使用盘驱动器的温度或压力的变化中发生这些空隙或气泡的尺寸的变化，则流体的体积将改变，并且相对于 周围物体的体积大小。 柔性膜将产生增加的流体体积的增加的压力。 膜基本上起弹簧的作用，其弹簧力由流体的体积增加产生的压力或伴随着流体体积的增加而克服。 发生这种情况时，膜的弹簧力被克服，膜松弛并形成气囊，有效地增加容纳润滑液的体积，并防止其逃逸或被迫离开轴承的内部区域。 以这种方式，流体保持在轴承中并且不会进入周围的大气，也不会从轴颈轴承区域中流失，使得当温度降低或压力下降时，流体动力轴承不那么有效。

    摘要： Hydrodynamic bearing having a shaft relatively rotatable with respect to a surrounding sleeve and having a thrust plate on one end thereof rotating in a recess of the sleeve. The shaft is preferably interrupted by a equi-pressure groove accessing a central reservoir in the shaft and having journal bearings defined by herringbone patterns above and below the groove to stabilize and provide stiffness to the cartridge. The stiffness of the cartridge is further enhanced by a thrust plate carried at one end of the shaft and rotating in a recess of the sleeve and being used to define thrust bearings on either surface thereof.

    摘要： Thus, if a shock or other disturbance to a disc stack spindle bearing assembly occurs that tilts the bearing assembly, the resulting motion is both a tilting, and a motion which is axial. If a shock axially moves the hub assembly, only an axial motion occurs. Thus the system has a non-linear behavior. Pursuant to this invention, when a tilting disturbance occurs, and some of it is dissipated in a net axial movement at a different frequency, energy is subtracted out of the system with motion that is not linearly related to the disturbance was that created it.

    摘要翻译： 因此，如果发生对盘式主轴轴承组件的冲击或其它干扰，从而使轴承组件倾斜，则所产生的运动既是倾斜又是轴向的运动。 如果冲击轴向移动轮毂组件，则仅发生轴向运动。 因此，系统具有非线性行为。 根据本发明，当发生倾斜干扰并且其中一些在不同频率的净轴向运动中消散时，能量被从系统中减去，其中与产生干扰的线性关系不是线性相关的运动。

    摘要： A device comprises a recordable disc, a substrate adjacent to the recordable disc, and an actuation mechanism fixed to the substrate. The recordable disc includes a base layer and a recordable layer on the base layer. Additional electrodes or magnetic components may be placed on the base layer to provide electromagnetic or electrostatic forces to rotate the recordable disc when acted on by the actuation mechanism. As an example, the invention may utilize MEMS techniques in order to integrate a disc and motor of a disc drive as a common component.
