摘要： Methods of compensating for repeatable runout in a disk drive are provided. The disk drive includes a data storage disk, a transducer adjacent to the disk, a primary actuator for positioning the transducer over a first range of movement, and a secondary actuator for positioning the transducer over a second range of movement that is less than the first range of movement. Estimates are made of the position of the secondary actuator in the second range of movement. Data is read from the disk via the transducer. A position error signal is determined based on the read data. Positioning of the transducer by the primary actuator is controlled based on the estimated position of the secondary actuator in the second range of movement and based on the position error signal to compensate for repeatable runout.

摘要： A method and apparatus for determining embedded runout correction values when self-servo writing or partial self-servo writing is disclosed. In one embodiment, a disk surface, which has servo information written thereon, is provided. The servo information is grouped into 1x servo sectors and 2x servo sectors, and the 1x servo sectors and the 2x servo sectors form a plurality of tracks. A read head servos on the 1x servo sectors associated with a track. Both position error signals due to repeatable runout for the 1x servo sectors and information related to position error signals due to repeatable runout for the 2x servo sectors are determined, while servoing on the 1x servo sectors. Embedded runout correction values for the 1x servo sectors and the 2x servo sectors are calculated.

摘要： Methods, systems, and computer-storage media for improving the freshness, or the apparent freshness, of search results are described. In an embodiment, the first portion of search results presented on a search results page are based on responsiveness to the search query and a second portion of results describe only recently published documents that are responsive to the search query. In an embodiment, a more recent version of the document, which is not directly used to determine responsiveness, is used to build the caption for a search result. Another way to make search results appear fresh is to include a publication time within the search result caption. In one embodiment, the publication time is generated by calculating a point in time between when a document is first added to a search index and the previous time the search engine visited the site where the document was found.

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.
