Abstract
A hub has a disc concentrically mounted about the hub for rotation with the hub. The hub has a body portion with a first axial end, a second axial end and a surface extending between the first and second axial ends. A flange is disposed at the second axial end of the hub and supports the magnetic disc. A clamp is disposed about the body portion of the hub proximate the first axial end of the hub. The clamp and the flange clamp the disc for rotation with the hub. The first axial end of the hub includes a sufficient number of slots communicating with an inner surface of the clamp such that the clamp is removable by applying a radial force to the inner surface of the clamp through the slots to attain a minimum radial displacement of the clamp which exceeds a maximum radial interference between the hub and the clamp and such that strain induced in the clamp is less than a desired percent so the clamp remains unbroken upon being radially displaced.
