Abstract

The intensity of slider-lubricant interaction is characterized by the amount of lubricant transferred from free lubricant region to bonded lubricant region in this study. The effect of electrostatic force on the slider-lube interaction is investigated by comparing the intensity of lubricant transferring under the same flying height but different electrostatic force conditions. Bump disks are used to calibrate slider and ensure the consistency of flying height under different experimental conditions. Results indicate that the slider-lubricant interaction can be increased significantly when sufficient interface voltage is present at the head-disk interface. The amount of lubricant transferred across the head-disk interface is found to increase with the increase in the applied interface voltage
