Abstract

A disk drive apparatus including a drive motor with disks separated by annular spacers disposed around a spindle. The disks are held in place by an annular hub which is held in place by a shaped disk clamp that is shaped to apply substantially equal forces to equally spaced locations around the annular hub. The disk clamp is fastened to the spindle and T-shaped load tabs that apply force to the annular hub. The annular hub has a conical surface and the conical angle is greater than the angle the T-shaped load tabs assume when deflected when fastened to the spindle.
