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 a radially-loaded, snap-fit disc mounting ring associated with each disc. The disc mounting rings include disc contact features for interaction with the inner diameters of the discs, and hub contact features for axially positioning the discs and associated disc mounting rings relative to the spindle motor hub. Various embodiments of the disc mounting ring are disclosed.
Claims14
A disc stack, comprising:
- a spindle motor having a hub;
- one or more discs mounted on said hub;
- and
- disc mounting means associated with each disc for axially and radially fixedly positioning the disc relative to the spindle motor hub.
A disc drive comprising:
- a spindle motor hub;
- one or more discs mounted to the spindle motor hub;
- and
- a disc mounting system for mounting the discs to the spindle motor hub, the disc mounting system further comprising:
- a disc mounting ring associated with one of the discs;
- and
- a plurality of disc contact features on an outer circumference of the disc mounting ring, the disc contact features being configured such that the position of the associated disc is axially and radially fixed relative to the spindle motor hub solely by the disc contact features.
A disc mounting system for mounting one or more discs to a spindle motor hub, the discs having upper and lower planar surfaces, the disc mounting system comprising:
- a disc mounting ring to be associated with one of the discs;
- and
- a plurality of disc contact features on an outer circumference of the disc mounting ring, each disc contact feature being configured to axially and radially fix the position of the associated disc relative to the spindle motor hub without contacting either of the planar surfaces of the associated disc.
