  • Write pole trailing edge partial side shield
    Patent number: 8339741
    Abstract: A magnetic writer has at least a write pole with a first partial side shield and a second partial side shield. The write pole has a leading edge and a trailing edge along an air bearing surface (ABS) and a first side and a second side along an axis orthogonal to the ABS. The first partial side shield is separated from the first side of the write pole and extends from adjacent the write pole from the trailing edge to a location intermediate that trailing edge and the leading edge.

  • SELF-ALIGNED, TRAILING EDGE PARTIAL SIDE SHIELD AND METHOD OF MAKING
    Publication number: 20100321835
    Abstract: A magnetic writer includes a write pole, a first partial shield and a second partial shield. The write pole has a leading edge, a trailing edge, a first side and a second side. The first partial side shield is located on the first side of the write pole, and the second partial side shield is located on the second side of the write pole. The first partial side shield and the second partial side shield extend along side of the write pole from the trailing edge to a location intermediate that trailing edge and the leading edge so that the first partial side shield and the second partial side shield do not shield the leading edge.
