- 論文の詳細を見る
The lubricant, perfluoropolyethers (PFPEs), has been modeled and analyzed based on a coarse-grained bead-spring model. A ultrathin lubricant film with a thickness of 1-2 nm is coated on a disk to lubricate the head disk interface (HDI) of hard disk drives (HDDs). The retention performance of the lubricant film is studied, which is important to avoid a direct contact between the head and disk. The replenishment performance is also studied, which is essential to repair the lubricant film ruptured by a contact of the head. Finally, the typical phenomenon of touch down-take off hysteresis during the contact between sliders and disks is confirmed and analyzed because of the nanoscopic interactions in the HDI.
