摘要： An air bearing slider used with a thin film magnetic head is formed with a corner recess and a taper at the leading edge. The taper is disposed between the corner recess and one side of the slider. A central polygon-shaped recess is bounded by pads which are joined by a connecting section. In an alternative embodiment, a recess at the leading edge separates the taper into sections. In another embodiment, a second corner recess is provided at the leading edge and the taper is disposed between the first and second corner recesses. The shaped recesses and tapers improve the flying characteristics of the slider and enhance air bearing stiffness. A single etch process is used to form the recesses and side reliefs of the slider.

摘要： An air bearing slider is designed with two rails and a central pad that provide positive air bearing regions to the air bearing surface of the slider, and three recess regions that are etched to a constant depth. The rails are identical and are symmetrically disposed relative to a central longitudinal axis. Each rail includes three sections: a pitch adjustment pad, a leg, and a roll adjustment pad. The pitch adjustment pad provides a balanced pressure distribution at the leading edge and optimizes the overall pitch angle of the slider. The leg extends from the pitch adjustment pad and generates counter-pressure that partially opposes the load applied by the suspension. The roll adjustment pad extends from the leg and generates an air bearing force that compensates for roll generated during slider operation. This air bearing slider design achieves constant flying height and less vertical and pitch stiffness, which will result in low contact force for pseudo-contact applications.
摘要翻译：空气轴承滑块设计有两个轨道和一个中心衬垫，它们为滑块的空气轴承表面提供正空气轴承区域，以及三个凹陷区域，这些凹槽区域被刻蚀成恒定的深度。轨道是相同的并且相对于中心纵向轴线对称地设置。每个轨道包括三个部分：俯仰调节板，腿部和滚动调节板。俯仰调节垫在前缘提供平衡的压力分布，并优化滑块的总俯仰角。腿从间距调节垫延伸并且产生部分地与由悬架施加的负载相反的反压力。辊调节垫从腿部延伸并产生补偿滑块操作期间产生的辊的空气轴承力。该空气轴承滑块设计实现了恒定的飞行高度和较小的垂直和俯仰刚度，这将导致用于伪接触应用的低接触力。

摘要： The air bearing surface of an air bearing slider is configured with a taper formed at the slider leading end and a rail that is formed with a base and two legs. One leg extends from the base partially toward the trailing end. The other leg extends from the base to the trailing end and is integrally formed of a rectangularly shaped section and one or more polygon-shaped sections. Inner and outer recesses are defined and separated by the rail, such that the slider is effectively insensitive to changes in ambient pressure, particularly from variations in altitude, so that a substantially constant flying height can be maintained.

摘要： An air bearing slider for a magnetic head is defined by a leading edge and a trailing edge and has a central longitudinal axis extending from the leading edge to the trailing edge. A pair of side pads, and a center pad between the side pads that is disposed substantially on the center axis, are formed on the air bearing surface of the slider. A first central recess having a T-shaped configuration is etched to a first depth, preferably in the range of 5-30 micro-inches with reference to the air bearing surface. A second major recess portion is etched to a second depth in the range of 60-150 micro-inches. The air bearing surface is configured for high load applications and maintains a flat flying height profile. The configured slider is particularly useful with small size sliders, such as picosliders.

摘要： A sub-ambient pressure air bearing slider is configured with longitudinal air-bearing rails that have angular side recesses near the trailing end of the slider. Sub-ambient pressure regions formed within the side recesses during disk operation oppose the asymmetrical lift forces which cause undesirable roll. The slider provides improved roll and flying height characteristics.

摘要： A negative pressure air bearing slider is provided with side rails, a central negative pressure cavity between the side rails and one or more relief vents at the leading edge of the slider. The side rails extend fully or partially from tapered regions at the leading edge of the slider to the trailing edge of the slider. Air bearing pads disposed adjacent to the front tapered regions and/or the slider trailing edge may be configured with the side rails. By virtue of the slider design, variations in flying height and roll are minimized.
