摘要： An air bearing surface of a slider is described. In one embodiment, the air bearing surface comprises a center channel. The air bearing surface further comprises a plurality of side channels, wherein at least one side channel of the plurality of side channels is open to the center channel, and a plurality of pocket areas. The center channel, the plurality of side channels, and the plurality of pocket areas are configured to allow air to flow along the center channel toward the trailing edge of the ABS, such that a change in ambient pressure and a change and relative velocity of a head assembly with respect to a data storage medium of a data storage device would not significantly affect the fly height of a head assembly utilizing the ABS.

摘要： An air bearing burnish slider burnishes very small asperities and cleans the loose particles that adhere to the magnetic recording media. The slider applies a controllable contact force to effectively burnish disk asperities or partially attached particles. In addition, the slider cleans the loose particles effectively while flying in a stable fashion. In a low pitch design, diagonal rails push particles away from the disk surface and trailing edge pads contact the disk at lower linear velocities. Rail pads retain loose contamination and debris in their pockets and burnish asperities. Another design provides a milder burnish force and flies in a high pitch configuration. The trailing edge pads provide stable contacts and the rails help in sweeping away debris. In both designs, the contact forces can be controlled by adjusting linear velocities. A step taper at the leading edge provides a pitch-producing lift force.
摘要翻译：空气轴承抛光滑块抛光非常小的凹凸，并清洁附着在磁记录介质上的松散颗粒。滑块应用可控的接触力来有效地抛光磁盘粗糙度或部分附着的颗粒。此外，滑块可以以稳定的方式有效地清洁松散的颗粒。在低间距设计中，斜轨将颗粒推离盘表面，后缘垫以较低的线速度接触盘。轨道垫在其口袋中保持松散的污染和碎屑，并且消除粗糙。另一种设计提供更温和的抛光力并以高间距配置飞行。后缘垫提供稳定的触点，导轨有助于扫除碎屑。在这两种设计中，接触力可以通过调整线性速度来控制。在前缘的阶梯锥形提供产生俯仰的提升力。

摘要： A magnetic recording disk drive achieves continuous contact recording with a head-suspension assembly that compensates for the moment generated from an adhesive force between the head carrier or slider and the disk. The slider pivot point, which is the point where the load force is applied to the flexure that supports the slider, is located closer to the front end of the slider than the net force applied by the air-bearing surface of the slider when the disk is rotating at its operational speed. This assures that the net air-bearing force generates a moment about the pivot point to partially counteract the flexure moment and the moment generated from the adhesive force between the disk and the slider's contact pad.
摘要翻译：磁记录盘驱动器通过头悬挂组件实现连续接触记录，该组合补偿从头托架或滑块与盘之间的粘合力产生的力矩。滑块枢转点，其是负载力被施加到支撑滑块的挠曲件的点，位于比由滑块的空气轴承表面施加的净力更靠近滑块的前端的位置，当盘正在以其运行速度旋转。这确保净空气轴承力围绕枢转点产生力矩，以部分地抵消弯曲力矩和由盘和滑块的接触垫之间的粘合力产生的力矩。

摘要： A compliant, flexible air bearing slider (ABS) reduces the contact forces between the slider and disk, thereby reducing excessive burnishing and wear and increasing the reliability of the slider. According to an embodiment, an ABS has at least one “compliance-enhancing feature” which reduces the bending mode vibration frequency of the slider. By causing the slider to flex, and bringing the bending mode vibration frequency closer to the pitch 2 eigenmode frequency, coupling of the different vibration modes can be obtained. Thus, the different vibration modes can effectively dampen each other and result in reduced contact forces between the slider and disk.
摘要翻译：兼容柔性的空气轴承滑块（ABS）可减少滑块和圆盘之间的接触力，从而减少过度抛光和磨损，并提高滑块的可靠性。根据实施例，ABS具有至少一个“柔顺增强特征”，其降低了滑块的弯曲模式振动频率。通过使滑块弯曲，并使弯曲模式振动频率更接近于本征模式频率，可以获得不同振动模式的耦合。因此，不同的振动模式可以有效地相互阻尼并且导致滑块和盘之间的接触力减小。

摘要： An embodiment of the invention is a slider with a lift pad and a thermal protrusion pad in which the heads are located. The lift pad is located immediately in front of the thermal protrusion pad and is designed to achieve the flying characteristics needed for normal operation of the disk drive. The thermal protrusion pad includes a heater which is used to protrude the pad for burnishing-on-demand and/or for thermal fly-height control. The thermal protrusion pad is designed to generate very little lift so that protruding the thermal protrusion pad does not significantly increase the lift experienced by the slider. An alternative embodiment uses two overcoat thicknesses on the ABS surface with the thermal protrusion pad having a thin overcoat and the lift pad having a thicker overcoat.
