摘要： Techniques for disk failure control involve determining the number of failed disks in a Redundant Array of Independent Disks (RAID). The techniques further involve comparing the number of failed disks with a predetermined threshold; and in accordance with a determination that the number of failed disks exceeds the predetermined threshold, setting at least one non-failing disk in the RAID into a protection mode to prevent the at least one non-failing disk from being disconnected. Such techniques facilitate prevention of the user data loss in the RAID.

摘要： A disk clamp for clamping a number of magnetic hard disks within a disk drive has a plurality of balance weight holes and a coined index mark for use as a reference in balancing the hard disks after assembly. The disk clamp also has a coined profile located adjacent or around the balance weight holes in order to provide uniform circumferential clamp force by the disk clamp. The disk clamp has a profile that places the inner region of the disk clamp in the plastic deformation region at a certain specified clamping force at the center of the disk clamp.

The chucking unit includes a lower horizontal part, a vertical part and an upper horizontal part. The lower horizontal part extends from the lower portion of the central boss outwards in the horizontal direction. The vertical part is bent from the outer end of the lower horizontal part upwards. The vertical part extends in a direction inclined outwards. The upper horizontal part extends from the upper end of the vertical part inwards in a horizontal direction.

摘要： A method of compensating for an imbalance of a hard disk drive includes biasing a plurality of disks in one direction with respect to a rotational shaft of a spindle motor hub, measuring an amount of imbalance of the plurality of disks with respect to the rotational shaft of the spindle motor hub, and compensating the amount of imbalance of the plurality of disks by hitting the hard disk drive in the opposite direction to the one direction in which the plurality of disks are biased to reduce the amount of imbalance with an amount of impact predetermined based on a measured imbalance amount.

摘要： Faulty engagement due to low surface precision of the engaging surfaces of a center core of a disk cartridge and a drive spindle is resolved. The center core 10 is positioned on the drive spindle 20 in a state where the center core 10 is in point contact with the drive spindle 20 at a minimum of three spots upon chucking. A minimum of three protrusions 10d are provided on the bottom surface of the center core 10, and lower ends P of the protrusions 10d are in point contact with the upper surface 21a of the drive spindle 20.

摘要： A shaft secured to a hub is inserted and rotatably supported in a sleeve secured to a base. A dynamic pressure groove is formed in the inner peripheral surface of the sleeve, and lubricant is sealed between the shaft and the sleeve. The rotation of the shaft causes dynamic pressure to generate in the lubricant due to the dynamic pressure groove, supporting the shaft floatingly. The crystallized-glass sleeve allows heat generated in a coil to be hardly transferred to the shaft, thereby reducing the variations in the clearance between the shaft and the sleeve due to temperature changes to a minimum in cooperation with the crystallized-glass sleeve with a low thermal expansion coefficient. Finishing accuracy of the bearing surface can be improved by chemical polishing. Consequently, the rotation accuracy can be improved and the leakage of lubricant due to the variations in the clearance can be prevented.
摘要翻译：固定到轮毂的轴被插入并可旋转地支撑在固定到基座上的套筒中。在套筒的内周面形成有动压槽，润滑剂被密封在轴与套筒之间。轴的旋转导致由于动压槽而在润滑剂中产生动态压力，浮动地支撑轴。结晶玻璃套筒允许在线圈中产生的热几乎不能传递到轴上，从而由于与具有低的结晶玻璃套管的温度变化而降低了轴和套筒之间的间隙的变化热膨胀系数。通过化学抛光可以提高轴承表面的精加工精度。因此，可以提高旋转精度，并且可以防止由于间隙的变化引起的润滑剂泄漏。

摘要： A disc-loading device includes a loading arm, a holding device, a guiding rail, and a guiding slot. The loading arm has a first end and a second end. The first end is connected to and movable along the guiding rail. The second end has a roller inset into the guiding slot. Due to the guiding function of the guiding rail and the guiding slot, the loading arm is able to shift along the guiding rail or rotate around its axis. The holding device for holding the disc is provided on the loading arm by means of rotatory movement with respect to the loading arm.
