ABSTRACT:
A disc clamp with a varying peripheral wall height at its outermost diameter. Variation of the peripheral wall height results in a circumferentially varying stiffness modulus of the disc clamp at specific circumferential positions relative to the position of multiple mounting screws which attach the central mounting portion of the disc clamp to the spindle motor hub. Varying the stiffness modulus of the disc clamp circumferentially results in even distribution of the clamping force about the contact surface of the disc clamp.
