摘要： An HGA loader which utilizes sub-ambient air pressure to move a magnetic head of the HGA relative to a test surface. The HGA is mounted to a clamp and located adjacent to a nozzle. The nozzle draws in air through an orifice to create a sub-ambient pressure region below the suspension. Ambient air pressure will flow into the sub-ambient void created by the nozzle located below the suspension beam of tge HGA. The air flow will move the suspension beam away from the disk surface and unload the HGA. The level of the sub-ambient pressure and the separation between the head and disk can be varied by a computer controlled regulator valve. The loader can be used in a flying height tester where calibration is obtained by taking optical data while varying the flying height by changing the sub-ambient pressure. The sub-ambient pressure created by the orifice causes the HGA to bend about its natural pivot point or the bend radius of the suspension or load beam. In doing so, the loader does not create an additional slider angle during a test procedure nor does it introduce any mechanical sliding motion which could generate debris.
摘要翻译： HGA装载机利用次环境空气压力相对于测试表面移动HGA的磁头。 HGA安装到夹具并且位于喷嘴附近。 喷嘴通过孔口吸入空气以在悬浮液下方产生低于环境压力的区域。 环境空气压力将流入由位于tge HGA的悬架梁下方的喷嘴产生的亚环境空隙。 空气流将使悬挂梁从盘表面移开，卸载HGA。 通过计算机控制的调节阀可以改变副环境压力的水平和头部与盘之间的分离。 装载机可以用在飞行高度测试仪中，通过改变低于环境压力的方式改变飞行高度，通过拍摄光学数据获得校准。 由孔口产生的次环境压力导致HGA围绕其自然枢转点或悬架或负载梁的弯曲半径弯曲。 在这样做时，装载机在测试过程中不会产生额外的滑块角度，也不会引入可能产生碎片的任何机械滑动运动。
