摘要： A disk drive includes a data storage disk, a transducer, a micro actuator, a coarse actuator, and a controller. The micro actuator is configured to position the transducer relative to the disk over a first range of movement. The coarse actuator is configured to position the micro actuator relative to the disk over a second range of movement that is larger than the first range of movement. The controller is configured to control positioning of the transducer by the coarse actuator and the micro actuator in a track following operation, and in a seek operation responsive to a seek command. The controller is also configured to calibrate its positioning of the transducer by the micro actuator responsive to receipt of the seek command and prior to seeking the transducer from an initial track to a target track.

摘要： A suspension for a HGA includes a suspension flexure and an out rigger. The suspension flexure has a tongue region having a first flexure part in a tip portion thereof for mounting a trailing edge of a slider and a PZT mounting region for mounting PZT elements. One end of the out rigger is connected to the suspension flexure, and the other end of the out rigger has a rigger support portion which extends above the tongue region so as to support the leading edge of the slider. The structure of the out rigger is capable of stiffening the tongue region of the suspension flexure and, in turns, avoiding the deformation problem and the dimple separation problem during the manufacturing process or in vibration or shock events. The invention also discloses a HGA with the suspension, manufacturing methods of the HGA and a disk drive unit having such HGA.

摘要： Altitude sensing systems and/or methods for fly height adjustment in disk drive devices are provided. In certain example embodiments, a PZT-type pressure and/or altitude sensor may be located on the side of the disk drive proximate to the disk edge. When the disk rotates, the air flow generated by the disk will deform the PZT element of the sensor. The PZT element will generate a voltage in response to this deformation. Calibrations may be performed to compensate for altitude changes (e.g. the air inside of the disk drive will become thin and the air resistance will be reduced at higher altitudes). Also, the output sensitivity of the PZT element may change with the altitude change. After the altitude is sensed by the PZT element in the sensor, the servo motor may use this signal to calculate and/or adjust the dynamic fly height (DFH) and/or fly height of the read/write head.
摘要翻译：提供了用于磁盘驱动装置中的高度感测系统和/或飞行高度调整方法。在某些示例性实施例中，PZT型压力和/或高度传感器可以位于磁盘驱动器的靠近磁盘边缘的一侧。当盘旋转时，由盘产生的空气流将使传感器的PZT元件变形。 PZT元件将产生响应于该变形的电压。可以进行校准以补偿高度变化（例如，磁盘驱动器内部的空气将变薄并且在较高海拔处降低空气阻力）。此外，PZT元件的输出灵敏度可能随高度变化而变化。在传感器中PZT元件检测到高度之后，伺服电机可以使用该信号来计算和/或调整读/写头的动态飞行高度（DFH）和/或飞行高度。

摘要： In accordance with various embodiments, a rotatable member is mounted to a spindle hub so that initial servo data previously provided to the rotatable member are eccentrically offset with respect to a rotational center of the spindle hub. Compensation vales are determined to characterize said offset, after which final servo data are provided to the rotatable member in relation to the initial servo data and the determined compensation values. The final servo data are nominally concentric with the rotational center of the spindle hub.

摘要： Certain example embodiments described herein relate to a micro-actuator for use with an HGA and/or disk drive device. A substantially U-shaped frame may include a cavity capable of receiving a slider. The frame may include two segmented, flexible side arms and a bottom support arm at least partially defining the cavity. Each segmented side arm may have a PZT element mounted on an outer surface thereof facing away from the cavity, and each may include a lower portion proximate to the bottom support arm and an upper portion disposed at an end opposing the bottom support arm. The lower portion and the upper portion may be at least partially separated by a gap. Accordingly, micro-actuators having better resonance and servo performance, reduced difficulties associated with the slider/micro-actuator mounting process, and/or better shock performance may be provided.
