Abstract
A disc pack assembly having a top cover and a bottom cover which together define a housing that contains the magnetic disc and hub assembly. An opening in the bottom cover is closed by a removable cover. The opening in the bottom cover provides access for the drive spindle which engages and rotatably supports the disc and hub assembly when the pack without the removable cover is mounted on a computer. The magnetic memory disc and hub assembly is afforded limited axial and radial movement within the housing when the removable cover is removed, but the removable cover includes a retaining ring which both supports and fixes the disc and hub assembly in the housing by engaging the hub through the opening when the removable cover is in place on the pack.
