A magnetic head for use in magnetic data storage systems is provided. The magnetic head includes a substantially non-magnetic writer gap layer and pair of magnetic poles separated by the writer gap layer. A first of the poles includes a first layer formed of a CoNiFe alloy that has a saturation magnetic moment greater than 2.1 Tesla. Methods of fabricating such a head are also disclosed.

A writer pole and a method for fabricating a writer pole is disclosed. The method comprises fabricating a conductive seed layer on a gap substrate and then fabricating a nonmagnetic feature on the seed layer where the nonmagnetic feature has a top layer and a plurality of sides. The seed layer and nonmagnetic feature are covered with photoresist. A window is fabricated in the photoresist, exposing a portion of the nonmagnetic feature and a portion of the seed layer, thereby exposing a top portion and a side portion of the nonmagnetic feature and exposing a portion of the seed layer. The portion of the seed layer in the window area is removed from the gap substrate. A pole is fabricated on the top and side portions of the nonmagnetic feature in the window area.

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.
