在开发硬盘驱动器时，有必要在操作期间保持润滑剂尽可能厚。为此，我们研究了不同形状的接触滑块下的薄膜磁盘的润滑剂损失，通过使用带有内置椭偏仪的滑针滑动试验。我们比较了滑动销与球形，平面圆形，平面正方形，和双平轨表面。结果表明，平销下的润滑损失小于球面销下的润滑损失，双平轨销下的润滑损失最小。结果表明，对于接触式记录系统，滑块的水平和垂直形状必须仔细选择。
In developing hard disk drives, it is necessary to keep lubricant as thick as possible during operations. For this purpose, we studied lubricant loss under different-shape contact-sliders on thin-film magnetic disks by using transparent-pin sliding tests with a built-in ellipsometer. We compared sliding pins with spherical, flat circle, flat square, and double-flat-rail surfaces. We found that lubricant loss was smaller under flat pins than under the spherical pin, and the smallest under the double-flat-rail pin among flat sliders. The results show that the horizontal and vertical shapes of sliders must carefully be selected for contact recording systems.
