摘要： The present invention is directed towards a disk drive that comprises at least one head carrying assembly that includes an actuator arm, a suspension attached to the actuator arm, and a head carried by the suspension. Each head is positioned upstream of its actuator arm. This reversed-flow orientation reduces head vibration and disk power requirements.

摘要： A rotary microactuator includes a stationary electrode formed on a substrate, a movable electrode in proximity to the stationary electrode, a flexure mechanically connecting the stationary electrode to the movable electrode, and a plurality of limiters anchored to the substrate. Each limiter has an in-plane limiter portion and an out-of-plane limiter portion. The in-plane limiter portion limits movement of the movable electrode to a predetermined in-plane distance in a direction parallel to a surface of the substrate. The out-of-plane limiter portion limits movement of the movement of the movable electrode to a predetermined out-of-plane distance.

摘要： A rigid magnetic recording disk drive includes a vacuum pump attached to the disk drive housing for removing air from within the housing so that the disk drive is operated at a reduced internal gas pressure. The pump motor is controlled by control circuitry that receives an input signal representative of the pressure within the housing to enable the pressure to be maintained within a predetermined reduced pressure range. Because spindle motor current has been directly correlated with internal pressure, a signal representative of the spindle motor current is used as the input to the pump control circuitry. The pump control circuitry also prevents the pump from turning on until the spindle motor has reached its stable operating speed, and from turning on when the disk drive is reading or writing data. Because of the reduced internal pressure the disk drive operates at a significantly higher disk RPM with only a minimal increase in power consumption and without any increase in track misregistration.
摘要翻译：刚性磁记录盘驱动器包括附接到盘驱动器壳体的真空泵，用于从壳体内去除空气，使得盘驱动器以减小的内部气体压力运行。泵马达由控制电路控制，控制电路接收代表壳体内的压力的输入信号，以使压力保持在预定的减压范围内。由于主轴电动机电流与内部压力直接相关，因此使用代表主轴电机电流的信号作为泵控制电路的输入。泵控制电路还防止泵开启，直到主轴电机达到其稳定的运行速度，并且在磁盘驱动器正在读取或写入数据时打开。由于内部压力降低，磁盘驱动器以明显更高的磁盘RPM运行，功率消耗只有最小的增加，轨道配准不增加。

摘要： A micro-actuator suitable for a piezoelectric film is described. A slow deformation and a rapid deformation are repeatedly produced in a piezoelectric film by generating a first voltage pattern V1 having an essentially sawtooth waveform between a pair of electrodes on one side of a wall-like member and a second voltage pattern V2 having an opposite polarity to that of the first voltage pattern V1 between a pair of electrodes on the other side of the wall-like member. As a result, the wall-like member responds by moving slowly in a first direction and rapidly in a second direction. An object placed on the wall-like member is moved in the first direction, because the object can follow the slow movement of the wall-like member but cannot follow its rapid movement.

摘要： A data storage device with improved data storage densities, coupled with lower hard error and write-inhibit events is described. A feed-forward write inhibit (FFWI) method enables data tracks to be written more densely. Alternatively, the FFWI method may reduce the hard error and write inhibit events to improve data storage performance. A concept of virtual tracks enables the FFWI method to be applied to the writing of circular data tracks with non-circular servo tracks, or to the writing of non-circular data tracks with PES data from circular servo tracks—in both cases, improvements to performance and/or storage densities are enabled. The FFWI method may also be applied to the case of both non-circular servo and data tracks.
