ABSTRACT:
A disk file data disk stack assembly is clamped using a preloaded heat shrink ring that has an interference fit with the assembly hub. In addition to an inner diameter slightly smaller than the cooperating hub surface, the shrink ring has a full or extended outer cylindrical surface and a reduced area inner cylindrical surface and a reduced area axial end surface to permit effective heat transfer to the ring with minimal conductive heat transfer to the hub and clamping element to enable a differential temperature for effecting shrink ring removal when required.
