Abstract
A transducer for servoing on data or separate servo information is fabricated with two adjacent magnetoresistive (MR) elements stagger connected such that each MR element senses one-half of the data magnetic transition track or separate coded servo tracks. Each MR element is magnetostatically biased by a soft magnetic film formed as a portion of its adjacent MR element material.
