Certain example embodiments relate to techniques for more precisely adjusting the spacing between a head and a disk in a disk drive device. A spindle motor of a disk drive device may be electrically isolated from at least the base plate by means of, for example, a nonconductive adhesive. Circuitry for monitoring and/or applying a voltage to the head and/or to the disk to control an amount of spacing between the head and the disk may be provided. In certain example embodiments, such circuitry may monitor the disk voltage and then apply an appropriate voltage bias to the head to control the spacing therebetween electrostatically. In certain other example embodiments, such circuitry may monitor the head voltage and then adjust the spindle voltage accordingly. In still other example embodiments, the disk voltage and the head voltage may be controlled and/or adjusted based on a known voltage differential so that a precise disk/head voltage potential is achieved.
