Abstract
In a method for negatively biasing a slider with respect to a disk to reduce slider wear and provide burnish rate control a negative bias voltage is generated between the slider and the disk surface respectively, the negative bias voltage causing slider/disk contact wear to occur on the disk instead of on the slider.
