Abstract
A hub and spindle assembly for an interchangeable, removable disk of a disk drive. The spindle assembly includes means for driving the hub assembly, matingly attached and removably engaged thereto, so as to rotate the disk coupled to the hub. The hub assembly includes surfaces for engaging an accurately machined rotational surface of the spindle assembly and force engaging means for ensuring mating contact of the hub assembly surfaces with the spindle assembly and for ensuring removeable engagement. The hub and spindle assembly minimize runout such that the Read/Write heads track an essentially circular disk track, even if the disk is removed, reinserted or placed on a different spindle of the same type.
