摘要： An air bearing surface of a slider, which achieves low crown sensitivity is described. In one embodiment, the air bearing surface comprises a center channel and a plurality of side channels, wherein at least one side channel of the plurality of side channels is open to the center channel. The center channel and the plurality of side channels are configured to allow air to flow along the center channel toward the trailing edge of the ABS, such that there is low crown sensitivity.

摘要： A dual etch depth slider air bearing surface includes a front pad disposed along the front and partially along the sides of the slider and a rear pad partially disposed along the rear of the slider, wherein a skewed center rail connects the front pad to the rear pad. Extending above the rear pad is a V-shaped ABS pad and extending above the front pad are two leading edge ABS pads that are separated by a channel towards the longitudinal center of the slider. The design enables the slider to fly much higher over the landing zone of the disk than at the data zone and provides for a steep take off profile followed by a rapid descend over the data zone.

摘要： A shallow etch at the trailing edge rail that allows the slider to fly closer to the recording medium and exhibit less sensitivity to roll. The slider includes a support structure and at least one rail having side edges and an air bearing surface raised above the support structure. At least one of the rails comprises a magnetic element disposed on the support structure. The edges of the rail adjacent to the magnetic element are etched to minimize the fly height of the magnetic element over the disk while preventing collision of the rail with the disk during roll conditions. The etched features of the rail create relieved trailing edge portions where the edges of the rail adjacent to the magnetic element are lower than the air bearing surface but are higher than the support structure. The shallow etch in the air bearing surface minimizes the difference between the minimum mechanical slider/disk spacing and the magnetic head/disk spacing which in turn allows optimization of transducer spacing. The edges of the air bearing surface adjacent the magnetic element are shortened by reactive ion etching or ion milling.

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。
