Abstract:
1. A system for assembling a hard disk drive, comprising: an enclosure; a motor mounted to the enclosure, the motor having an axis and a hub assembly that is rotatable about the axis relative to the enclosure, the hub assembly having an axial end with an axial feature formed in the axial end, the axial feature being concentrically aligned with the axis; a disk for information storage and retrieval mounted to the hub assembly for rotation therewith, the disk being concentrically aligned with respect to the axial feature to reduce any initial imbalance therein; an actuator assembly mounted to the enclosure for movement relative to the enclosure and the disk, the actuator having a head gimbal assembly with a head for reading data from and writing data to the disk; and a guide member with an outer surface and a protrusion, the outer surface being adapted to support the disk for transfer to the hub assembly, and the protrusion being adapted to concentrically align the disk with the hub assembly via the axial feature, such that the guide member concentrically aligns with the hub assembly with respect to the axis.
