대기압 저감에 따른 헤드/디스크 인터페이스의 트라이볼로지 특성 분석
Effect of Reduced Ambient Pressure on the Tribological Behavior of Head/Disk Interface
초록
Optimum tribological performance of the head/disk system is critical in maintaining reliable data processing in a hard disk drive. Particularly, as the flying height of the slider continues to decrease with increasing recording density, frictional interaction between the slider and the disk need to be better understood. In this work the effect of reduced ambient pressure on the tribological behavior of the head/disk interface is presented. It is found that surface damage of the components can be accelerated by reducing the ambient pressure. This method may be utilized to assess slider/disk compatibility of newly developed systems in short time.
