摘要

分子薄的润滑膜用于硬盘驱动器中磁头磁盘接口的润滑。薄膜厚度减少到1-2纳米,以尽量减少磁间距,并需要优化,精确的设计,以获得足够的润滑。然而,到目前为止,还没有普遍适用的方法来研究这种薄膜。因此,我们开发了一种高灵敏度的剪切力测量方法,并将其应用于涂覆在磁盘表面的润滑膜的粘弹性测量。在本文中,我们回顾了该方法并总结了迄今为止我们所证明的有用发现。

Nanorheometry of Molecularly Thin Liquid Lubricant Films Coated on Magnetic Disks
Molecularly thin lubricant films are used for the lubrication of head disk interfaces in hard disk drives. The film thickness is reduced to 1-2 nm to minimize the magnetic spacing, and optimal, precise design is required to obtain sufficient lubrication. However, until now, there was no generally applicable method for investigating such thin films. Therefore, we developed a highly sensitive shear force measuring method and have applied it to the viscoelastic measurement of lubricant films coated on magnetic disk surfaces. In this paper, we review the method and summarize the useful findings we have demonstrated so far.
