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 including a composite disc spacer that maintains the discs in a fixed radial relationship to the spindle motor hub. The composite disc spacer includes a wedge member which supports a plurality of axially extending fingers which include inwardly and outwardly facing surfaces that bear against the spindle motor hub and against the bores of the discs to maintain the discs in a fixed concentric relationship to the spindle motor hub. The composite also has a spacer that extends about the wedge member to provide fixed relative axial spacing of the discs. The wedge member and the spacer interlock to facilitate handling of the composite disc spacer during assembly.
