Abstract
A hub assembly in a disc drive includes a hub rotatable about an axis. The hub has a first axial end and a second axial end. A plurality of hub mounted elements are disposed about the hub, including a support member connected to the second axial end of the hub, a disc, a clamp which frictionally engages the hub, and a spring located axially between the clamp and the support member. The clamp and the support member exert opposing axial forces on the disc to hold the disc for rotation with the hub. The spring includes a first axial surface and a second axial surface opposite the first axial surface. The first and second axial surfaces are non-planar to provide resilience in the axial direction.
