  • Electrical isolation of read sensors during fabrication
    Patent number: 10224066
    Abstract: A method includes depositing a plurality of layers over a substrate. The layers include read sensor layers and an electrically conductive layer substantially coplanar with the read sensor layers and substantially surrounding the read sensor layers. The electrically conductive layer is in contact with at least one of the read sensor layers. The electrically conductive layer provides an electrical path between the at least one of the read sensor layers and ground. The method further includes forming an isolation structure around the read sensor layers by removing a portion of the electrically conductive layer substantially surrounding the read sensor layers. The isolation structure is substantially coplanar with the read sensor layers and substantially surrounds the read sensor layers. The isolation structure breaks the electrical path between the at least one of the read sensor layers and the ground.

  • 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.

  • Edge barrier to prevent spin valve sensor corrosion and improve long term reliability
    Patent number: 6600637
    Abstract: A magnetic data storage and retrieval system has a bottom shield, a first half gap positioned on the bottom shield, a sensor layer positioned on the first half gap, a second half gap positioned on the sensor layer; and a top shield positioned on the second half gap. The sensor layer includes a magnetoresistive sensor having sidewalls and a barrier surrounding and in direct contact with the sidewalls of the magnetoresistive sensor.
