A magnetoresistive sensor requires only two electrical connections to operate. The magnetoresistive sensor uses a hammerhead design and a barber pole array. Blocking capacitors are used to define two signal paths, one for a DC sense current, and one for an AC data signal. The blocking capacitors provide an electrical short to AC signals across wing regions of the magnetoresistive sensor. The blocking capacitors are fabricated directly upon a wafer which carries the magnetoresistive sensor.
