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： Air bearing sliders that achieve fly height profiles which allow improved areal density and file capacity. The sliders include angled features in such a way that they align with the air skew at textured zones on a disk. The angled features are selected to create a first air pressure distribution at first predetermined radii of the recording medium and a second air pressure distribution at second predetermined radii of the recording medium. The spacing profile may be obtained by skewing the whole or a portion of one or more rails with respect to the air bearing slider edges. In designs with a center rail, the spacing profile may be customized by skewing the center rail. Further optimization may be provided by altering the taper of the rail widths. Still further, the entire slider can be mounted with a skew with respect to the suspension to achieve the required fly height profile variations rather than skewing one or more of the rails. The exact shape of the profiles are optimized to the file's magnetic and mechanical needs and improve capacity and density in files that have constant texture (or no texture) throughout the whole disk surface.
摘要翻译：空气轴承滑块实现飞行高度分布，可提高面积密度和文件容量。滑块包括成角度的特征，使得它们与盘上纹理区域处的空气偏斜对齐。倾斜特征被选择以在记录介质的第一预定半径处产生第一空气压力分布，并且在记录介质的第二预定半径处产生第二空气压力分布。可以通过相对于空气轴承滑块边缘倾斜一个或多个导轨的整体或一部分来获得间隔分布。在具有中心导轨的设计中，间距分布可以通过偏斜中心导轨进行定制。可以通过改变轨道宽度的锥度来提供进一步优化。此外，整个滑块可以相对于悬架倾斜安装，以实现所需的飞行高度分布变化，而不是倾斜一个或多个导轨。配置文件的精确形状针对文件的磁性和机械需求进行了优化，并提高了整个磁盘表面的纹理（或无纹理）的文件中的容量和密度。

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。
