摘要： An air bearing slider according to the present invention provides a programmable slider wherein the fly height of a the read/write head may be conveniently controlled using electrical signals. In an air bearing slider according to the present invention, the rear of the slider is made to fly lower by altering the angle of attack of a rear air bearing region. In one embodiment of the present invention, a slider configuration includes a first air bearing region (31) at the leading edge of the slider and a second air bearing region (32) at the slider's trailing edge. The first air bearing region includes a tapered region (37). A deformable central region (33), including a non air bearing surface, joins the first and second air bearing regions and controls the relative angle between the air bearing surfaces. The relative angle is adjusted by deforming the central region using a layer of e.g. piezoelectric material which overlays the central region. A conventional read/write head is placed on the rear portion of the second air bearing region.

摘要： The fly height of read/write heads in multiple disk drives is dynamically adjusted to optimum fly height by a servo loop. The fly height is sensed in real time with a harmonic ratio fly height detector and compared to an optimum or reference fly height. The suspension system of each head is adjusted in accordance with the departure of the fly height of that head from the optimum fly height. The adjustment of the suspension system is accomplished by bonding a piezoelectric film to the flexible suspension arm carrying each head. The fly height is corrected for both radial and circumferential error as the head changes radial and circumferential position relative to the disk surface. The reference fly height, to which each head is moved by the servo loop, may be selectively changed in the fly height servo operation. This can be done to lift the heads away from the disk surface during track seek mode or disk drive sleep mode. The reference fly height can also be changed to lower the heads towards the disk surface during error recovery mode.
摘要翻译：多个磁盘驱动器中读/写磁头的飞行高度通过伺服回路动态调整到最佳飞行高度。使用谐波比飞行高度检测器实时感测飞行高度，并与最佳或参考飞行高度进行比较。每个头部的悬挂系统根据该头部的飞行高度从最佳飞行高度的偏离来调节。悬挂系统的调整是通过将压电膜粘合到携带每个头部的柔性悬挂臂来实现的。当头部相对于盘表面改变径向和周向位置时，对于径向和周向误差来校正飞行高度。可以在飞行高度伺服操作中选择性地改变每个头部被伺服回路移动的参考飞行高度。这可以在磁道寻道模式或磁盘驱动器睡眠模式下将磁头抬离磁盘表面。也可以改变参考飞行高度，以便在错误恢复模式期间将磁头降低到磁盘表面。

摘要： The present invention relates to a paper sheet counting apparatus including a hopper in which a plurality of paper sheets are filled in a stacked state, a transport mechanism that feeds the paper sheets filled in the hopper to a transport path one by one, and transports the paper sheets along the transport path, a sensing unit having at least a counting sensor for counting the paper sheets and a recognizing part for recognizing the paper sheets, and a stacker in which the paper sheets fed from the transport path are stacked.
The transport mechanism includes a drive roller constituting an inside of a turn portion for changing a direction of the transport path, a plurality of pinch rollers that bias the paper sheet against an outer peripheral surface of the drive roller, and a turn guide plate arranged between the pinch rollers to guide the paper sheet along an outer periphery of the drive roller. The turn guide plate is formed such that a front edge of the paper sheet transported to the turn portion is guided to a contact portion between a pinch roller arranged on a downstream side among the pinch rollers and the drive roller.
The transport path has a bent portion formed on an upstream side of the counting part and the recognizing part so that a thin and hard foreign article other than the paper sheets cannot pass therethrough.

摘要： The invention generally relates to a system for achieving reduced head-media spacing (HMS) in a hard disk drive (HDD) by providing active control over the positioning of a read/write head relative to a rotating magnetic data recording and reading surface of a disk. The system is configured to monitor and adjust positioning of the read/write head in real, or near-real time during disk rotation to maintain the HMS between a magnetic transducer of the read/write head and the disk surface within a defined range, generally between 1.0 nm and 10.0 nm, and, in some embodiments, approximately 4.3 nm. The system replaces the conventional an air bearing surface (ABS) design with a fully active suspension to maintain the head flying height within the desired range. The system further allows for each of the magnetic transducer and disk surface to be to be devoid of any overcoat or lubricant layers.
