Abstract
A hub for a disk drive assembly including an upper member formed of a first material; and a lower member formed from a second material that supports and reinforces the upper member. The second material has a rigidity greater than the rigidity of the first material. Additionally, a disk drive assembly may be performed by combining a hub, a disk media mounted to the hub and a clamping mechanism attached to the hub and providing a clamping force to the disk media.
