    摘要： An air bearing slider for supporting a magnetic transducer comprising a pair of coplanar side rails on the sides of an air bearing surface of the slider and a center rail along the central region of the air bearing surface to form recessed areas between the rails which extend from the leading to the trailing end of the slider. All the rails have a tapered section at their leading ends. The side rails have a width that does not exceed the width of the side rails at the leading end, and the side rails extend only part way to the trailing end of the slider. The width of the center rail is small at the leading end and greatest at the trailing end of the slider, where the transducer is supported.

    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。
