Magnetic write head having electrically biasable structures

摘要

An apparatus according to one embodiment includes a resistive link coupled to both an electrically conductive bus and an electrically conductive structure, the electrically conductive structure being positioned proximate to a media bearing surface. An apparatus according to another embodiment includes an array of transducers; an electrically conductive bus; and resistive links electrically coupled between the electrically conductive bus and at least one of: each of a plurality of electrically conductive structures, and at least some of the transducers.
