Abstract
A disc clamp for a disc drive used to secure a disc stack in position when the disc is mounted to a hub. The disc clamp is annular with a central opening and has three tabs. The three equidistantly spaced tabs extend radially inward from the circumferential edge of the central opening. The disc clamp is resiliently flexible and has a continuous annular disc contact region adjacent to an outer circumferential edge. The disc clamp also has at least three screw openings each for receiving a screw fastener to fasten the disc clamp to the hub in the clamping position. The disc clamp resiliently flexes in the clamping position to cause the annular disc contact region to bear against the surface of the outermost stacked disc to clamp the disc stack against radial and axial movement.
