Relationship between Take-off Behavior of Hard-disk Slider and AE Signal
하드디스크 슬라이더의 부상 특성과 AE신호의 관계
Abstract
Acoustic emission(AE) signal has been widely utilized to monitor the interaction at the head/disk interface. In this work the relationship between the AE signal and the state of contact between the slider and the disk is presented. Results of the FFT analyses of the AE signal could be used to better understand the interfacial interaction. Also, it was found that wear particles affect the AE signal. Therefore, the signal can be used to monitor the wear particle presence at the interface.
