摘要： This motor is arranged to rotate an annular member, and includes a stationary portion including a stator, and a rotating portion arranged to be rotatable about a central axis extending in a vertical direction. The rotating portion includes a hub arranged to extend in an annular shape around the central axis; a magnet including a pole surface arranged radially opposite to the stator; and a yoke to which the magnet is fixed. The hub includes a hub annular portion in the shape of a circular ring and arranged above the stator, and a flange surface on which the annular member is arranged. The yoke includes a yoke increased thickness portion arranged radially outside of the magnet; and a yoke decreased thickness portion arranged to have a radial thickness smaller than that of the yoke increased thickness portion, and arranged axially above the yoke increased thickness portion. The yoke decreased thickness portion is fixed to the hub annular portion through press fitting.

摘要： Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck, a plurality of storage mediums, and a plurality of disc separator plates. Each disc separator plate includes one or more mounting pad surfaces, at least one of the surfaces having a protrusion. The disc separator plates are coupled to one another and the base deck via the mounting pads, with the disc separator plates in a stacked arrangement. The protrusion or protrusions facilitate alignment of the plurality of disc separator plates in the stacked arrangement, and mitigate contact between the storage mediums and the disc separator plates.

摘要： 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.
