PCT No. PCT/US93/07652 Sec. 371 Date Dec. 15, 1994 Sec. 102(e) Date Dec. 15, 1994 PCT Filed Aug. 13, 1993 PCT Pub. No. WO95/05660 PCT Pub. Date Feb. 23, 1995Magnetic hard discs are clamped on a disc spacer by integral spacer flanges. The spacer's diameter is slightly larger than the disc interior diameter thereby providing a radial clamping load. The discs are fit onto the spacer either by providing a small gap in the annulus of the spacer ring or by first cooling the spacer. The entire disc spacer and disc assembly is mounted on the drive spindle as a unit. A disc clamp clamps the assembly to a spindle flange by means of a lip on the interior of the spacer. The lip is preferably spaced axially below the top surface of the top most disc so that both the clamp and the clamp's mounting screw can be placed axially below the top surface of the top disc to thereby provide a low profile spindle/disc stack assembly. In another embodiment, the lip has an inclined surface to impart an additional radial load force to the top disc.
