摘要： A recording head for a disk drive with a load/unload mechanism has an air bearing on one surface. The air bearing comprises a patterned set of three air bearing pads, at least five shallow pockets and one deep pocket. A narrow gap extends from the deep pocket and separates leading ones of the air bearing pads and shallow pockets from each other. The air bearing pads have unique, step-shaped geometry and the rear pad is virtually free of any shallow area. This configuration gives the air bearing superior performance characteristics over prior art designs with load/unload mechanisms.

摘要： A dual etch process for forming an air bearing slider design with three etch depths. For one embodiment the first etch forms the leading and trailing step regions and the second etch forms the lateral step regions. The combination of the first and second etches form the negative pressure region.

摘要： An air bearing slider for use in carrying a transducer adjacent a recording medium exhibits reduced sensitivity to variations in roll, crown, and skew. In one embodiment, the slider comprises an air bearing slider having a pair of substantially coplanar side rails disposed along the sides of the air bearing surface so as to form a recessed section between the side rails. The recessed section is open at both the leading and trailing ends of the slider while each side rail has a tapered section or etched step at the leading edge of the slider. One rail carries the transducer and extends for the entire length of the slider body. The rail without a transducer extends from the leading edge toward the trailing edge, but does not extend all the way to the trailing edge. Under some skew, accessing, and crash stop impact conditions, the resulting slider roll causes the flying height of the inactive rail to drop. By proper selection of the length and width of the inactive rail, the roll is biased such that the fly height of the inactive rail remains higher than that of the active rail even under worst case conditions. Therefore, minimum slider to disk spacing is larger than it would be for a slider design in which all rails extend the entire length of the slider.

摘要： An air bearing slider having reduced mask misalignment sensitivities. For one embodiment, the air bearing slider has three etch surfaces formed by a dual etch process. The leading and trailing step regions are formed by a first etching step. The lateral step regions, adjacent to the air bearing pads, are formed by a second etching step. The negative pressure region is formed by both the first and second etching steps.

摘要翻译：用于承载邻近记录介质的传感器的空气轴承滑块表现出对辊，表冠和歪斜变化的敏感性降低。在一个实施例中，滑块包括一个空气轴承滑块，其具有沿着空气轴承表面的侧面设置的一对基本上共面的侧轨，以便在侧轨之间形成凹陷部分。凹陷部分在滑块的前端和后端都是打开的，而每个侧轨具有在滑块前缘处的锥形部分或蚀刻步骤。一个轨道承载换能器并且在滑块体的整个长度上延伸。没有传感器的导轨从前缘朝向后缘延伸，但不会一直延伸到后缘。在某些偏斜，进入和碰撞停止冲击条件下，产生的滑块导致非活动导轨的飞行高度下降。通过适当地选择不活动轨道的长度和宽度，辊被偏置，使得即使在最坏情况条件下，非活动轨道的飞行高度也保持高于活动轨道的飞行高度。因此，最小滑块到磁盘间距大于滑块设计中的所有滑轨延伸滑块的整个长度。
