Track seeking and the slider-disk space variation during track seeking
are becoming more and more serious concerns when technology moves to
0.8 similar to 1.5 mu in 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 indica
te that the suspension's vibration during track seeking plays an impor
tant role in the flying height vibration of slider. Furthermore, resul
ts indicate that the likely zone of slider-disk impact can be revealed
by monitoring the resistance and the VCM current waveform simultaneou
sly. A model is proposed also to explain the relationship of flying pa
rticles inside disk chamber, the slider's dynamic performance during t
rack seeking and the flying particles induced HDI failure.
