Abstract

A drive level measurement of flying height modulation and a demonstration of slider-disk contact control was conducted. The results of the flying height modulation strongly agree with those obtained from a Laser Doppler Vibrometer (LDV) measurement. The modulation was mainly caused by curvature caused by disk clamping. Furthermore, feedback control of a slider-disk contact was successfully demonstrated. Friction force was controlled at a small value to maintain the slider so that it flew over the disk in the light contact regime.
