摘要： A technique for preventing damage to ball bearings in a small form factor device where the drive motor has at least one crash stop ring disposed about the shaft and inside the rotor of the motor. The crash stop ring is dimensioned to permit only a small amount of movement of the rotor relative to the shaft. The permitted movement must be less than the minimum movement which would cause damage to the elements of the ball bearing. In an alternative embodiment, a rotor includes a flange extending in the radial direction from the rotor. A piezoelectric ring is rigidly mounted on both sides of the flange to engage one of the planar surfaces of the flange when the piezoelectric ring is in the relaxed state. With two such crash stop rings disposed so that the rings can engage both planar surfaces of the flange, the rotor is effectively clamped between the two piezoelectric crash stop rings whenever the piezoelectric crash stop ting is disconnected from the power source used to contract the piezoelectric material in a direction parallel to the axis of rotation of the rotor.

摘要翻译： 一种用于防止在小型装置中损坏球轴承的技术，其中驱动马达具有围绕轴设置并且位于马达转子内部的至少一个止动环。 防撞环的尺寸设计为仅允许转子相对于轴的少量运动。 允许的运动必须小于会损坏球轴承元件的最小运动。 在替代实施例中，转子包括从转子沿径向方向延伸的凸缘。 当压电环处于松弛状态时，压电环刚性地安装在凸缘的两侧上，以接合凸缘的一个平面。 通过设置两个这样的碰撞止动环，使得环可以接合凸缘的两个平面表面，只要压电碰撞停止与用于收缩压电材料的电源断开，则有效地将转子夹在两个压电紧急停止环之间 在平行于转子的旋转轴线的方向上。

摘要： A suspension for a read/write head of a disk drive is fixed to a side wall of an arm. If two heads are to be suspended, a first suspension for one head and a second suspension for the other head are fixed to opposite side walls of the arm. Since the suspension is fixed to the side wall of the arm, there are no screw heads protruding or projections formed by hot staking on the top and the bottom surfaces of the arm and it is not necessary to make screw holes which extend from the top surface or the bottom surface into the arm perpendicularly to these surfaces. Thus, the vertical thickness of the head carriage assembly can be decreased.

摘要： Embodiments of the present invention help to achieve a solder joining structure having high reliability, in which even if a componential material of a flange of a feed-through of a sealed magnetic disk drive is an iron-based material such as Kovar™, and a componential material of a base of the drive is an aluminum-based alloy, leakage of low-density gas is dramatically reduced. According to one embodiment, a base has a stepped portion in the inside of a periphery of an opening, and an inclined surface extending to the outside of the base is formed at an edge of a surface of the stepped portion, on which a flange of a feed-through is placed, thereby when the stepped portion of the base is joined by soldering with the flange of the feed-through, a solder fillet is formed not only in the inside of the base, but also in the outside thereof.

摘要： Embodiments of the present invention help to provide a magnetic disk drive in which the base and the lid are securely welded together, so that the low-density gas sealed therein is protected from leakage. According to one embodiment, the peripheral surface of the rib of the base is machined to form the surface, which is free of electrocoating and weld surface. The outer lid, which completely conforms to the contour of the base, is placed on the rib, and the laser beam is directed onto the outer lid. Thus the position of laser beam irradiation varies within only ±0.05 mm for both the base and the lid. Laser welding in this manner yields the bead invariably, which makes the enclosure completely sealed without helium leakage.

摘要： In a disk drive actuator head stack assembly, magnetic transducers including magnetoresistive (MR) read heads are connected to a current source and configured to provide an MR sensor current to each MR head wherein the direction of current flow for the MR sensor current in each MR head is the same relative to the actuator for all of the MR heads in the actuator head stack. This configuration allows all of the MR heads in the head stack assembly to be initialized simultaneously by applying a homogeneous magnetic field to the head stack assembly, thus providing the capability of initializing the MR heads at the actuator or disk drive level rather than requiring that the MR heads be initialized individually.
