摘要： A method of machining a complex pattern into the air bearing surface of a magnetic head slider includes the steps of forming a die with a diamond surface which has a pattern which is a reverse image of the desired pattern for the surface of the slider; placing the die with the pattern of the die facing the surface of the slider; placing an abrasive slurry between the die and the surface of the slider; applying a pressure between the die and the surface of the slider; and ultrasonically vibrating the die and the slider reciprocally with respect to one another to cause the abrasive slurry to grind the desired pattern into the surface of the slider.

摘要： An apparatus, method, and article of manufacture to separate a slider from a slider row in which it was manufactured. The apparatus comprises an articulating robot including a stage which may be moved in X-Y coordinate directions and an articulating arm that may be used to place rows of sliders on the stage. The articulating arm incorporates a rotating effectuator unit mounted at the end of the arm, the effectuator being used to pick up individual slider rows, the tray in which they sit when first introduced to the robot, or any other item that needs to be positioned during the alignment of the rows. The apparatus includes sensors and a processing unit that may be used to detect and determine dimensional characteristics of an ABS surface of a slider integral to the row. The apparatus may also include a parting device for separating the slider from the row. In performing the method, a slider row is positioned on the stage in a manner that allows the ABS surface of a slider to be sensed by the sensors. Using the sensed data, the processing unit determines the location of the centroid of the ABS surface for the slider. The processing unit uses the centroid location of the ABS surface in establishing a parting position for parting the slider from the row.
摘要翻译：一种用于将滑块与其制造的滑块排分离的装置，方法和制品。该装置包括一个铰接式机器人，其包括可以在X-Y坐标方向上移动的平台和可用于将行滑块放置在平台上的铰接臂。铰接臂包括安装在臂的端部的旋转实验器单元，该实验器用于拾取单独的滑块行，当第一次引入机器人时，它们坐在其中的托盘或需要在其中定位的任何其它物品行的对齐。该装置包括传感器和处理单元，该处理单元可用于检测并确定与该行积分的滑块的ABS表面的尺寸特性。该装置还可以包括用于将滑块与行分开的分离装置。在执行该方法时，滑块行以允许滑块的ABS表面被传感器感测的方式定位在平台上。使用感测数据，处理单元确定滑块的ABS表面的质心的位置。处理单元使用ABS表面的重心位置来建立分离位置，以便从该行分离滑块。

摘要： A method and apparatus for texturing the air bearing surface (ABS) of a magnetic head of a hard disk drive includes juxtaposing the ABS with an ultrasonically-driven sonitrode having a diamond die end. An alumina slurry is disposed between the sonitrode and ABS at a slight pressure, with the slurry having a grit size of less than one micron. The sonitrode is then vibrated to agitate the slurry and thereby texture the head. If desired, a cavity can be formed in the die, with the cavity being a mirror image of a portion of the head, e.g., the sensing element, that is not intended to be textured.
