摘要： A disk clamp for clamping a plurality of disks within a disk drive has a single fastening hole located at its symmetrical center sized to pass the shaft of a screw having a head diameter larger than the fastening hole. The screw fastens the disk clamp to a motor hub supporting the plurality of disks. The disk clamp has a moat around the fastening hole, at a maximum diameter that is smaller than the head diameter of the head on the fastening screw. The moat may be circular, have spike trenches angled toward the fastening hole, or be spiral. The diameter of the spiral moat decreases in a clockwise or counterclockwise direction toward the fastening hole. The midsection of the disk which the screw head covers is biased at a negative angle toward the fastening hole forcing particles generated during assembly toward the fastening hole of the disk clamp.

摘要： A disk drive device includes a stationary member and a rotatable member rotatably supported by the stationary member about a rotation axis. The rotatable member includes a cylindrical part, which fits in a center hole of a recording disk, and a placement part protruding radially outward from the cylindrical part in a direction of the rotation axis. The cylindrical part includes an external thread groove formed on an outer peripheral surface thereof. The external thread groove engages with a thread groove of a clamper to clamp the recording disk. The cylindrical part includes a small inner-edge inclined surface, which is a tapered annular surface formed on an end of the cylindrical part so that the external thread groove begins forming from the small inner-edge inclined surface. The small inner-edge inclined surface has an inner circumferential edge having a diameter smaller than a thread bottom diameter of the external thread groove.

摘要： A hard disk drive disk clamp is described, in which flex is introduced into the clamp in the radial direction so that, for example, as the disk expands radially at a different rate than the clamp as the temperature increases, less distortion is affected to the disk because the clamp can flex radially. With less disk distortion there is less repeatable runout (RRO) and more precise track following. The disk clamp may have an I-shaped cross-section along the outer portion of the disk clamp, at the contact area with the disk, to provide the radial flex.
摘要翻译：描述了一种硬盘驱动器盘夹，其中挠曲沿径向方向被引入到夹具中，使得例如当盘随着温度升高时以与夹具不同的速率径向扩张时，较少的变形会受到因为夹具可以径向弯曲。随着磁盘失真的减少，可重复的跳动（RRO）和更精确的跟踪跟踪更少。磁盘夹具可以在与盘的接触区域处沿着盘夹的外部具有I形横截面，以提供径向弯曲。
