Abstract
Track seeking and the slider-disk space variation during track seeking are becoming more and more serious concerns when technology moves to 0.8-1.5 /spl mu/m gap flying-height. This paper reports results of in-situ experimental investigations of the slider's dynamic flying performance during track seeking. A partial erase method and a slider-disk resistance method were used in the investigation. Results indicate that the suspension's vibration during track seeking plays an important role in the flying height vibration of slider. Furthermore, results indicate that the likely zone of slider-disk impact can be revealed by monitoring the resistance and the VCM current waveform simultaneously. A model is proposed also to explain the relationship of flying particles inside disk chamber, the slider's dynamic performance during track seeking and the flying particles induced HDI failure.
