    摘要： A disc head slider is provided and includes a disc-facing surface. The disc-facing surface comprises an inside set of surface components that includes an inside cavity dam and an inside sub-ambient pressure cavity having an inside cavity floor. The disc-facing surface further comprises an outside set of surface components that includes an outside cavity dam and an outside sub-ambient pressure cavity having an outside cavity floor. The disc-facing surface also comprises a center set of surface components that is generally disposed between the inside and outside sets of surface components. The center set of surface components includes a center cavity dam and a center sub-ambient pressure cavity having a center cavity floor. The inside, outside and center sets of surface components are separate and disassociated from one another.

    摘要： Herein is disclosed a method and apparatus for reducing particle collection on a slider or gimbal tongue. The gimbal tongue is shaped so as to interact with airflow within a disc drive to direct particles away from the slider and gimbal tongue. The leading edge of the gimbal tongue overhangs the leading edge of the slider. As air current approaches such a geometry, a large pocket of slow moving, high pressure air is created just upwind of the slider. Thus, as particulate matter encounters this pocket, the matter is slowed and its momentum is partially dissipated. A vent is provided in the gimbal tongue. The vent permits an escape route for the particles to move to an area of lower pressure, located on the other side of the gimbal tongue.

    摘要翻译： 本文公开了用于减少滑块或万向节舌上的颗粒收集的方法和装置。 万向节舌片成形为与盘驱动器内的气流相互作用，以使颗粒远离滑块和万向节舌头。 万向节舌的前缘突出于滑块的前缘。 当气流接近这样的几何形状时，刚好在滑块的上风中产生一个缓慢移动的高压空气的大口袋。 因此，随着颗粒物碰到这个口袋，事情变得缓慢，其动量被部分耗散。 在万向节舌头上设有通风口。 排气口允许颗粒移动到位于万向节舌头另一侧的较低压力区域的逃生路线。
