摘要： 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.

摘要： An apparatus for minimizing axial and radial displacement of discs in a disc drive having a spindle motor hub rotatable about a central axis. The hub includes a substantially cylindrically shaped mounting surface at a selected radius about the central axis. The disc spacer comprises a substantially circular body having an inner surface at a first radius greater than the radius of the mounting surface, and a plurality of inwardly-facing spindle contact features projecting from the body. Each of the spindle contact features has a spindle contact surface at a second radius less than the radius of the mounting surface, with the spindle contact surfaces being operably configured to bear against the mounting surface when the disc spacer is coupled to the spindle motor hub. Preferably, intermediate portions of the body between adjacent spindle contact features deform to urge the spindle contact features toward the mounting surface.
