Abstract
A hard disk drive disk clamp is described, in which flex is introduced into the clamp in the radial direction so that, for example, as the disk expands radially at a different rate than the clamp as the temperature increases, less distortion is affected to the disk because the clamp can flex radially. With less disk distortion there is less repeatable runout (RRO) and more precise track following. The disk clamp may have an I-shaped cross-section along the outer portion of the disk clamp, at the contact area with the disk, to provide the radial flex.
