  • Electrodeposited high-magnetic-moment material at writer gap pole
    Patent number: 6778357
    Abstract: 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.
    Type: Grant
    Filed: October 24, 2001
    Date of Patent: August 17, 2004
    Assignee: Seagate Technology LLC

  • Self bucking servo transducer
    Patent number: 5461528
    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.
