Abstract
A servo head in a disc file data storage system includes a servo transducer and a coil which are connected so that noise induced by a nearby writing data head cancels. The servo transducer, mounted on a slider, reads information stored on a servo disc. The coil, also mounted on the slider, is connected to the servo transducer to produce an output signal so that noise signals induced in the servo transducer by operation of the data head tend to be canceled by noise signals induced in the coil by operation of the data head.
