    摘要： A hard disk drive establishes a roll static attitude (RSA) of a slider during operation to be zero during normal operation and to be non-zero during load/unload from a ramp. Specifically, a RSA bias mechanism such as a piezoelectric layer can be coupled to the slider suspension to bend the flexure of the suspension during load/unload so that the slider inner edge is higher than the outer edge. Consequently, any slider-disk contact that occurs during load/unload will be at the outer edge of the slider, where data is not expected to be on the disk.

    摘要翻译： 在正常操作期间，硬盘驱动器在操作期间建立滑块的滚动静止姿态（RSA）为零，并且在从斜坡加载/卸载期间将非零。 具体地，诸如压电层的RSA偏置机构可以耦合到滑块悬架，以在加载/卸载期间弯曲悬架的挠曲，使得滑块内边缘高于外边缘。 因此，在加载/卸载期间发生的任何滑块 - 磁盘触点将位于滑块的外边缘，其中数据不会在磁盘上。

    摘要： A self-contained OCR system includes a housing holding a scanner for outputting a digitized representation of information on paper documents, and a processor in the housing for executing an OCR module to generate ASCII text from the digitized representation. The housing also holds a hard disk drive for storing the text. External devices are not needed to transform the paper-borne text to electronically-stored text.

    摘要： A head slider for a disk drive storage device. The head slider is adapted to fly at the target height above the disk, reduce contamination by preventing particles from being trapped under the head slider, fly well in helium at low velocity and obtain a manufacturing tolerance so that multiple head sliders may be produced and function properly. The head slider has an internal cavity that is substantially enclosed by the air bearing surface. There are two gaps in the air bearing surface that are misaligned relative to the leading edge. The gaps aid in preventing particles from entering the cavity.

    摘要： A head slider for a disk drive storage device. In general, the head slider should fly at the target height above the disk without crashing onto the hard disk. The head slider has an outside flange that encloses a plateau and an inside flange that encloses a plateau. The two plateaus may have the same surface area or the outside plateau may have a greater surface area. Because of the design of the outside flange, the likelihood that the head slider will crash on the hard disk is reduced.

    摘要： An apparatus and method for reducing a suspension gram load to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, a gram load of the suspension is reduced to minimize the friction force during contact of the TE with the disk such that when the TE portion of the slider contacts the disk the bouncing motion of the TE with respect to the disk is reduced.

    摘要： A glide-height disk-tester operates with the test disk rotating at a predetermined constant rotational speed and uses a glide head with an electrically-resistive heater and a thermally-responsive protrusion pad located on its trailing end. The linear velocity of the disk relative to the slider maintains the slider at its nominal fly height, which is typically higher than any expected asperity. With no current applied to the heater, the protrusion pad is generally flush with the air-bearing surface of the slider. Increasing levels of current are applied to the heater, which causes movement of the protrusion pad toward the disk surface. When the pad contacts an asperity, the current level applied at the instant of asperity contact is recorded. The applied current level can be correlated to the glide height from a previous calibration process using a calibration disk with known calibration bump heights.
