Abstract
A disk drive assembly having a shallow or low profile construction. The assembly includes a drive spindle and drive cone for the diskette. The drive cone is mounted directly from a part of the frame or chassis of the assembly. The drive spindle is cylindrical having a bottom which is dished or raised upwardly providing a bottom recess. The bushing which contains the journal bearings for the spindle shaft extends into the recess so that overall dimension of the assembly is minimized.
