摘要： A disk drive includes a base, and a spindle motor coupled to the base. The spindle motor includes a hub defining an axis of rotation. The disk drive further includes a disk disposed about the hub and including a disk inner diameter biased against the hub at a contact location of the hub. The disk drive further includes a balancing element including a cylindrical portion disposed about the hub. The balancing element further includes a first cavity defining a first cavity centroid disposed on a same side of the axis of rotation as the contact location, and a second cavity defining a second cavity centroid disposed on a side of the axis of rotation opposite the first cavity centroid. The second cavity centroid is spaced apart from the first cavity centroid in a direction along the axis of rotation.

摘要： This application discloses a hard disk drive comprising a landing ramp mounted to a disk base including a slider limiter for at least one slider in the hard disk drive to limit movement of the sliders during a non-operational shock event while parked on the loading ramp. Each of the slider limiters includes a clearance zone configured so that when the slider contacts the slider limiter during the non-operational event, the read-write head remains out of contact with the slider limiter. The clearance zone may include a recess and/or a cutout. The clearance zone may include a recess and/or a cutout. The recess may take any shape, for example the recess may be a polygon and/or curved in cross section. The polygon may have at least two sides. The clearance zone may further include a radial bulge to further protect the read-write head during non-operational shock events.

摘要： A disk drive is disclosed comprising a disk, a spindle motor for rotating the disk, and a head actuated radially over the disk. A disk clamp clamps the disk to a hub of the spindle motor, wherein the disk clamp comprises a notch at a predetermined location along an outer diameter of the disk clamp. The disk is aligned non-concentric with the hub such that a center of the disk is aligned offset from a center of the hub toward the notch. The notch substantially counteracts an imbalance due to the non-concentric alignment of the disk with respect to the hub.
