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 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.
