摘要： An actuator assembly for a disc drive includes an E-block supported by a spindle for rotation about an axis and having an actuator arm supporting a transducer. An elongated yoke arm extends from the E-block. A motor rotates the E-block about the axis to position the transducer adjacent a selected track on the recording disc. The motor includes a voice coil supported by the yoke arm. A stop mechanism defines at least one of the inner and outer tracks of the disc and comprises at least one stop pin mounted to the disc drive housing and a stop surface on a distal end of the yoke arm for engaging the stop pin.

摘要： A method of manufacturing a disc drive actuator is provided. The method includes manufacturing a disc drive actuator and machining a peripheral surface of the actuator. The peripheral surface is machined to obtain a desired profile dimension and thereby reduce variations in resonance characteristics from one actuator to the next.

摘要： The instability of a cage in a precision ball bearing at high speeds may be eliminated by controlling the position of the cage. The control of a position of a cage is accomplished by forming three ball pockets or holes in the cage for the balls of the ball bearing assembly to a dimension that will result in a tight running fit between the ball and the ball pocket. A tight running fit between the ball and the cage is found in three of the ball pockets in a ball bearing assembly while the diameter of the large ball pockets or other remaining ball pockets is enlarged to provide a clearance between the balls and the cage which is at least twice the clearance between the ball and the guide ball pocket having the tight running fit, and preferably three to five times that clearance. When properly lubricated, the tight running fit will insure stabilization and control of the cage so that the cage remains stable at high rotational speeds.
摘要翻译：可以通过控制保持架的位置来消除高精度滚珠轴承中的保持架的不稳定性。保持架位置的控制是通过在滚珠轴承组件的滚珠的保持架中形成三个球窝或孔，以达到球与球袋之间的紧密配合的尺寸。在滚珠轴承组件中的三个球袋中发现球和保持架之间的紧密配合，而大的球窝或其他剩余的球窝的直径被扩大以提供滚珠和保持架之间的间隙，球与具有紧密配合的导向球袋之间的间隙的至少两倍，并且优选为该间隙的三到五倍。在适当润滑的情况下，紧密的运动配合将确保保持架的稳定和控制，使得保持架在高转速下保持稳定。
