ABSTRACT:
A disc mounting system for mounting the discs of a disc drive in a fixed radial relationship to the hub of a spindle motor. The disc mounting system includes curved spring elements, having a substantially C-shaped axial cross section, which are curved on a radius greater than the radius of the central opening of the discs. One or more spring elements are utilized with each disc, and assembly tooling is used to bend the spring elements so that the discs, with the opening of the C-shaped springs engaging the inner diameter of the discs, can fit over the hub of the spindle motor. The assembly tooling is then removed to allow the spring elements to partially straighten, firmly engaging the discs relative to the spindle motor hub in the radial direction. In a first embodiment of the invention, alternative mechanisms are disclosed for establishing the axial positions of the discs. In a second embodiment, a plurality of annular grooves are provided in the spindle motor hub and the spring elements engage both the discs and annular grooves in the spindle motor hub to fixedly locate the discs relative to the spindle motor hub in both the radial and axial directions. Fabrication of the spring elements from a shape-memory alloy is also disclosed.
