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 includes one or more axially-extending tubular members inserted radially between the outer diameter of the spindle motor hub and the inner diameter of the discs. Various mechanisms for ensuring a tight radial connection between the spindle motor hub and the discs are disclosed.
