Abstract
A servo head in a disk file data storage system includes two servo transducers which are connected so that noise induced by a nearby writing data head will cancel. The two servo transducers are located an equal distance from the data transducer. The pole tips of the first servo transducer are positioned to read servo information stored on an adjacent servo disk. The pole tips of the second servo transducer are oriented away from the servo disk surface to prevent the second servo transducer from reading an unwanted signal from the servo disk.
