A disk drive having spacers to compensate for disk warpage is described. The spacers are positioned on opposite sides of a disk with each spacer contacting the disk a different radial position relative to the center of the disk. The offset contact areas result in displaced moments on the disk, with respect to each other, when the spacers are clamped to the disk. The moments generated by the clamped spacers provide a torque on a warped disk to improve its flatness.
