ABSTRACT:
An apparatus comprises a storage medium, a head substrate, wherein the storage medium and the head substrate are separated by a gap, a plurality of electrodes separated from each other, and a support structure positioned in the gap for supporting some of the electrodes. An apparatus comprising a storage medium, a head substrate, wherein the storage medium and the head substrate are separated by a gap, a plurality of posts positioned in the gap, a layer of low friction material positioned on one end of each of the posts, is also described.
