Abstract: A spindle assembly (12) has a shaft (14) with at least two axially spaced expandable shaft sections (20, 22). The expandable shaft sections serve to couple the spindle to a bearing assembly (30, 32) having inner races (34, 36). The expandable shaft sections are expanded elastically and uniformly into retentive contact with the inner races to provide radial and axial support for the spindle assembly.

Abstract: A disk drive structure maximises the axial length available for mounting disks within a predetermined height such as dictated by a form factor. A cast aluminium box frame 12 is used which supports the spindle and actuator assemblies and forms a part of the head disk enclosure in cooperation with a drawn metal cover 10. The box frame captures the spindle 9 and actuator shafts 40 at each end to ensure maximum overall assembly stiffness and to minimise the axial length required by the structure supporting the spindle. The box casting geometry is angled to establish the casting/cover joint around the disks before the diameter of the disks parallel to the width form factor, so that only the thinner cover is interposed in the region where the disks most closely approach the form factor. The cover and box frame are sealed and secured to one another by a thin compliant tape 11 that does not contribute stress to the box frame during thermal cycling.
