摘要： A process for finishing a disc drive slider (22, 23) in which a pressure generator (38) applies multiple pressures (36) to the back surface of one slider while the front surface (25) of the one slider contacts a lapping surface (24) to form a finished front surface of the slider (22). The slider (22) is part of a substrate (20) having multiple unfinished sliders (22) formed in it. An etch process is used to etch trenches (32) in the substrate (20) aligned between the sliders (22) and to form webs (34) joining the sliders (22) together. After the sliders (22) are finished by lapping, the webs (34) are removed to separate the sliders (22). The multiple sliders are conveniently held together during the finished process and the etching process avoids damage to the sliders (22).

摘要： An apparatus and a method for measuring the force (GL) applied by an elastically flexible element (5;71,71') undergoing a pre-set elastic deformation, more specifically an element that carries a slider (3) and includes a thrust device that applies a force to the flexible element. The thrust device includes, for instance, a pneumatic nozzle (27;57,57';28) for applying a force (R) to an intermediate portion (4) of the thin plate, at a thrust section (K). A position sensor (30;80) detects the height (z) of the slider - indicativeof the deformation of the flexible element. The value (MF) of the moment of the applied torque when the height (ZF) of the slider indicates the pre-set elastic deformation of the flexible element, is utilized for calculating the force to be measured according to the formula GL = MF / L where L is the distance separating the slider from the section of weakness.

摘要： Disc drives are made with an actuator designed with at least one asymmetrical arm having two masses that move out of phase. The arm is modified by removing a portion of the higher-energy (longitudinal) side, the one with the greater total time-averaged strain energy. This modification reduces the phase difference between the first and the second arm, particularly for a relevant frequency range of interest. Disc drives made by this method exhibit a generally reduced out-of-phase motion, enhancing performance during seeking and track following, especially for arms with two heads that interact with surfaces of opposing discs.

摘要： A suspension limiter for limiting travel of a read/write transducer gimbal in a disc drive is disclosed that positively engages or interlocks with a feature of the load beam supporting the gimbal, or vice versa, to preclude disengagement of the limiter during an abnormal external shock event. One embodiment has a hook on the load beam that fits within a hole gimbal to interlock the two together. Another embodiment has a hook on the gimbal that fits within a hole in the load beam during a shock event. Another embodiment has tabs on the gimbal that hook over a notch in side fingers extending from the end of the load beam on either side of the gimbal. Another embodiment has a hooked tab on the load beam that extends through an aperture in the gimbal to interlock the gimbal and load beam together during a shock load event. Each of the embodiments prevents catastrophic plastic deformation of the gimbal during such events.

摘要： A system and method for controlling vibration of a piezoelectric microactuator (158) in a disc drive (110) are disclosed. The mechanical strain on the piezoelectric microactuator (158) is ascertained and fed back to a controller (190, 175) which provides an electrical signal to the piezoelectric microactuator (158) based upon the sensed strain. The electrical signal provided to the piezoelectric microactuator (158) produces a mechanical force on the microactuator (158), which counteracts the sensed strain. In one embodiment, a bridge circuit (179) is coupled to the piezoelectric microactuator (158). The bridge circuit (179) is adapted to sense a voltage across the piezoelectric microactuator (158) and to separate the voltage across the piezoelectric microactuator (158) into a voltage externally applied to the piezoelectric microactuator (158) and a voltage induced on the piezoelectric microactuator (158) by mechanical strain.

摘要： The air bearing design consists of four rectangular pads. Each pad features an open rectangular pocket located at the corner of the leading and inner (closer to the disc ID) edges. The pocket opens towards the slider's leading and inner edges. The increase in linear velocity from ID to OD dictates that the slider flies lower at ID than OD. The introduction of the open pocket can effectively offset the difference due to the linear velocity. As we move from ID to OD, the steps that the skewed airflow encounters change from the forward to reverse. Consequently, the lifting force generated by the air compression at the forward steps decreases, while the suction force produced by the air expansion at the reverse step increases, reaching a maximum at OD. Both of them offset the effect of the linear velocity, yielding a constant fly height profile from ID to OD. In addition, the open pockets toward the inner edge generate more air bearing compression for the incoming side flow, improving the ramp-loading dynamic stability under large roll static attitude. The open pocket can be either a step or ramp surface, and the number of pads can be varied. The air bearing design is scalable to achieve different fly heights.
摘要翻译：空气轴承设计由四个矩形垫组成。每个垫具有位于前端和内侧（更靠近盘ID）边缘的角部的开放的矩形袋。口袋朝向滑块的前缘和内边缘打开。从ID到OD的线速度的增加规定滑块在ID处比OD低。开放口袋的引入可以有效地抵消由于线速度的差异。当我们从ID移动到OD时，倾斜的气流遇到的步骤从前进到倒退。因此，由前进档中的空气压缩产生的提升力减小，而在反向阶段由空气膨胀产生的吸力增加，达到OD的最大值。它们都抵消了线速度的影响，从ID到OD产生了恒定的飞行高度分布。另外，朝向内边缘的开口袋对于进入的侧流产生更多的空气轴承压缩，从而提高在大的辊静态下的斜坡加载动态稳定性。打开的口袋可以是台阶或坡道表面，并且垫的数量可以变化。空气轴承设计是可扩展的，以实现不同的飞行高度。
