Abstract:
In one general embodiment, an apparatus includes a plurality of read transducers arranged in an array, and a plurality of biasing circuits. Each biasing circuit is coupled to a unique one of the read transducers. Each biasing circuit is configured to selectively reverse a direction of a read current applied to the read transducer associated therewith.
