Abstract
In recent years, it is necessary to reduce the lubricant film thickness in order to increase the capacity of the hard disk drives (HDDs). However, thinning of the lubricant film brings deterioration of the tribological characteristics in head-disk interface. In this study, we made the composite lubricant film and friction tests were conducted to evaluate friction characteristics. As a result, we confirmed the composite lubricant film showed lower surface energy, high bond rate and equal friction coefficient than conventional lubricant film.
