Abstract
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.
