A Study on the Surface Damage between Head/Disk Interfaces by Using AFM
AFM을 이용한 Head/Disk의 표면 파손에 관한 고찰
Abstract
In this work the surface damage of head and disk of a hard disk drive was analysed using an Atomic Force Microscope. The initial damage of the disk occurred by generation of extremely small wear particles. Also it was shown that wear particles tend to pile up near the front side of the slider. The surface damage mechanism of drag test and contact-start-stop test was found to be quite similar.
