    • A spindle motor assembly adapted for rotationally supporting a load about a base includes a rotor rotatably mounted on the base with its outer periphery capable of supporting a load, a stator and a plurality of magnets mounted on the outer periphery of the rotor. The stator includes a plurality of stator laminations with selective portions of the stator laminations forming stator cores. A plurality of magnets are mounted on the outer periphery of the rotor in an operating relationship with the stator cores. A plurality of conductors are wound on the stator cores. The stator includes a resilient covering located around the plurality of laminations and further having a routing means to route the conductors between the stator cores, an attaching means to attach the stator to the base and a connecting means. The connecting means includes a first connector block with a plurality of first conductor pads, with a first end and a second end. Ends of the conductors are connected to the first end of the conductor pads. A second connector block is mounted on the base, with the second connector block having a plurality of second conductor pads. The second end of the first conductor pads are connected to the second conductor pads of the second connector block.

    • An actuator arm assembly is provided in a disc drive. The disc drive includes a disc with a surface for storing information and a first actuator for moving the actuator arm assembly relative to the surface of the disc. The actuator arm assembly includes an actuator arm coupled to the first actuator, a load beam coupled to the actuator arm, a suspension coupled to the load beam and an air bearing coupled to the suspension. A transducer is mounted on the air bearing and positioned to access the surface of the disc. A second actuator is coupled to the air bearing and the load beam and is controllable to move the air bearing relative to the surface of the disc and relative to the load beam.

    • A disc drive cartridge is disclosed comprising a central actuator arm pivot hub mounting one magnetic pole, which in turn rotates within and overlaps a u-shaped upright base and sleeve supporting a second non-aligned magnetic pole. The system relies on the radial repulsive forces of the separate magnetic poles to achieve significant radial stability; in certain embodiments, attractive forces between axially aligned magnetic poles or a magnetic pole and a sleeve of high permeability magnetic material are also utilized to enhance the axial stability of the system. The rotating hub supports on one side one or more actuator arms and on the other side a coil of a voice coil motor, so that this magnetic bearing can be the central pivot for a very small compact and low noise disc drive cartridge.
    • 公开了一种盘驱动器盒,其包括安装一个磁极的中央执行器臂枢转毂,该磁极又在支撑第二非对准磁极的u形立柱底座和套筒内旋转并重叠。 该系统依赖于单独磁极的径向排斥力,以获得显着的径向稳定性; 在某些实施例中,也利用轴向对准的磁极或磁极与高磁导率磁性材料的套筒之间的吸引力来增强系统的轴向稳定性。 旋转轮毂在一侧支撑一个或多个致动器臂,另一侧支撑音圈电机的线圈,使得该磁轴承可以是用于非常小的紧凑且低噪音的盘驱动器盒的中心枢轴。
