Surface damage analysis of Head/Disk interface using AFM

AFM을 이용한 Head/Disk의 표면파손에 관한 고찰

In this work surface damage of head and disk of head disk drive was analysed using an Atomic Force Microscpoe. The initial damage of the disk occurred by generation of extermely small wear particles. Also it was show 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.
