摘要: A giant magnetoresistance-dual magnetoresistance sensor or reproduce head (GMR-DMR) comprising multilayers of alternating magnetic and nonmagnetic thin film layers arranged such that sets N sandwiched are formed on either side the center-most, conductive, layer, whereby layered structure operates in fashion a dual magnetoresistive exhibits magnetoresistance. Preferably outer-most thickness differs from remaining order to reduce self-bias level variance between outermost innermost layers. Sense current flow through GMR-DMR is induced by sensed fields generated changes detected as output voltage variations.
