ABSTRACT:
A disk drive spindle assembly including a rotatable hub and one or more disks having a central opening slightly larger than the cross dimension of the hub, so that the disk may freely fit over the hub. A flange extends radially outwardly from a lower region of the hub and defines an narrow, vertically extending annular support wall for supporting a disk along a uniform narrow contact region between the hub and the disk. A disk clamp clamps the disk against the support wall contact region. An annular concentric space, preferably defined by an elastomeric spacer structure which aligns the disk relative to an axis of rotation of the hub, spaces the disk away from the hub.
