  • Method of forming a write head with a write pole shield having a low saturation magnetization layer
    Patent number: 10593355
    Abstract: A recording head that includes a bearing surface and a write pole having a front surface that forms a portion of the bearing surface. The recording head also includes a side shield for the write pole. The side shield includes a low saturation magnetization cap layer having a front surface that forms a portion of the bearing surface. The side shield also includes a main side shield layer having a saturation magnetization that is higher than a saturation magnetization value of the low saturation magnetization cap layer.

  • Data writer gap material with decreased protrusion
    Patent number: 9734855
    Abstract: A data writer can have at least a write pole separated from a return pole by a non-magnetic lamination. The non-magnetic lamination may consist of first, second, and third non-magnetic materials that are each different and configured to provide a physical protrusion on an air bearing surface of less than 4 Angstroms.

  • Data writer with shaped write coil
    Patent number: 9715888
    Abstract: A data writer may be configured with at least a write pole continuously extending from an air bearing surface to a via. The write pole can contact at least one yoke that contacts the write pole. The write pole and yoke may each be disposed between and separated from a write coil that has a single turn and continuously extends to opposite sides of the write pole.

  • Data writer front shield with varying throat height
    Patent number: 9601136
    Abstract: A data storage device employing a data writer may configure the data writer with at least a write pole that is separated from a front shield on an air bearing surface. The front shield can be arranged to continuously extend from the air bearing surface a first throat height distal the write pole and a second throat height proximal the write pole with the first and second throat heights being different.

  • Data Writer with Yoke Shaped Write Pole
    Publication number: 20140300995
    Abstract: A magnetic element can be configured as a data writer with at least a write pole contacting a yoke and having an air bearing surface. The write pole may be shaped to match a paddle surface of the yoke that extends perpendicular to the air bearing surface and facing parallel to the air bearing surface.
