摘要： A head stack assembly includes an actuator including an actuator arm, a load beam coupled to the actuator arm, and a gimbal coupled to the load beam. The gimbal is formed of an electrically conductive material. The head stack assembly further includes a dielectric layer disposed upon the gimbal. The head stack assembly further includes a slider supported by the gimbal. The head stack assembly further includes slider conductive pads disposed upon the dielectric layer with the dielectric layer interposed between the slider conductive pads and the gimbal. The slider conductive pads are electrically connected to the slider. The head stack assembly further includes a ground conductive pad disposed upon the dielectric layer with the dielectric layer interposed between the ground conductive pad and the gimbal. The ground conductive pad is electrically connected to the slider and the gimbal for electrically grounding the slider.

摘要： Systems and methods are provided for mitigating interference in a wireless network to facilitate network performance. In an aspect, a method for transmitting wireless data packets is provided. The method includes receiving data packets from a wireless distribution network. The data packets are analyzed to determine if a subset of the data packets are to be suppressed in view of transmitter signal conditions and substituting null packets for the subset of data packets if the subset of data packets are determined to be suppressed.

摘要： A disk drive includes a sampled servo controller for periodically adjusting a control effort signal during a track-following operation based on embedded distributed position information and repeatable runout (RRO) cancellation values for reducing effects of RRO in the distributed position information during track following. A magnetic disk in the disk drive stores RRO information relating to predetermined RRO cancellation values for a data storage track. The RRO information for the data storage track includes at least one first data structure having a first predetermined number of data bits for representing an initial RRO cancellation value, and includes at least one second data structure having a second predetermined number of data bits associated with a respective subsequent RRO cancellation value. The first predetermined number of data bits is greater than the second predetermined number of data bits.

摘要： Disclosed is a head stack load comb used in the controlled loading of a head of a head stack assembly (HSA) onto a disk during the assembly of a disk drive. The HSA includes an actuator arm, a head, and a loading surface. The load comb includes a base structure and at least one ramp finger projecting approximately perpendicularly from the base structure. In order to load the head in a controlled manner onto the disk, the loading surface of the HSA is rotated along the ramp finger until the head is in a load position and then the base structure is actuated in a vertical direction such that the ramp finger is correspondingly actuated in the vertical direction towards the disk until the head is loaded onto the disk.
