Abstract
A multi-disk pack hard disk drive includes first and second spindle motor assemblies mounted one over the other on a base post. Each motor assembly may include a compact axial flux motor. The motor wiring for each may be routed within a structural cutout feature of the base post to an electrical connector at the base. A compact threaded disk clamp and motor hub interface may be implemented to further reduce the vertical height of the multi-disk pack assembly.
