Abstract
A load/unload ramp assembly for a hard disk drive includes a support plate having at least one interlock slot and a plurality of ramp units interconnected with the support plate. At least one of the ramp units includes an interlock structure that protrudes into a corresponding interlock slot of the support plate, and is configured to move within the interlock slot in response to shrinkage of the ramp unit upon cooling associated with manufacturing of the ramp assembly. The ends of the interlock slot may be configured to manage the shrinkage and/or to maintain design dimensions.
