摘要： A novel disk drive includes a top cover having a plurality of integral anchor tabs extending towards a disk drive base. Each of the plurality of anchor tabs includes a hooking surface that faces the top cover. The disk drive base includes a plurality of retention cavities, each of the retention cavities including a catching surface that faces away from the top cover. Each of the plurality of anchor tabs protrudes into a respective one of the plurality of retention cavities, and may be deformed so that the hooking surface of the anchor tab is in contact with the catching surface of the retention cavity.

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： There is provided a disk drive including a disk and an actuator. The actuator includes a first actuator arm. The first actuator arm has a region of reduced thickness between an arm longitudinal axis and a disk axis of rotation. An average thickness of the first actuator arm in the region of reduced thickness is less than an average thickness of the first actuator arm at an equal distance from an actuator axis of rotation but on an opposing side of the arm longitudinal axis. The actuator includes a suspension assembly having first and second flexible legs. The suspension assembly is coupled to the first actuator arm via the flexible legs. The second flexible leg is disposed further from the disk in a direction parallel to the disk axis of rotation than the first flexible leg and closer to the disk axis of rotation than the first flexible leg.

摘要： A disk drive includes an opaque cover secured to a base, where the opaque cover has an opening. A see-through insert, which includes an electrically conductive material, is affixed to the opaque cover over the opening. The electrically conductive material may be a coating applied to the see-through insert which, in one embodiment is a polymer coating having a certain surface resistivity. Alternatively, the coating's ESD-dissipative properties may be due to the presence of sputtered gold, sputtered indium tin oxide or a metal film. The electrically conductive material may alternatively be embedded in the see-through insert.

摘要： A stationary plate functions as a vibration damper and has an integrated air filtration guide. In one embodiment the stationary plate is disposed between two adjacent disks, and the guide comprises one or more grooves through which rotation-induced air may flow. In another embodiment, a plurality of stationary plates may be disposed between a plurality of disks, wherein each of the plurality of stationary plates has a grooved side through which the rotation-induced air may flow. In still another embodiment, the orientation of the grooves in the stationary plate is such that the rotationally-induced airflow impinges the disk drive's voice coil motor.
