    摘要: A method for forming a P3 layer with NiFe and alumina mask using resist shrink process for use in perpendicular magnetic write heads. The method includes forming a laminated layer, forming an alumina layer on top of the laminated layer, depositing a conductive layer onto the laminated layer, forming a plating frame on a gap layer. The plating frame has a trench defined by plating track, the alumina, laminated and conductive layers each including an area below the trench. The method further includes shrinking the trench, plating NiFe into a portion of the shrunk trench, stripping the plating frame, removing the conductive layer except the conductive layer formed below the trench, removing the alumina layer except the alumina layer formed below the trench, removing the laminated layer except the laminated layer formed below the trench and patterning the laminated layer formed below the trench.

    摘要: A perpendicular write head having a wrap around trailing shield for reducing stray field writing and adjacent track interference. A method for constructing such a write head allows for excellent control of side shield gap thickness and trailing shield gap thickness, and allows the ratio of side gap to trailing gap thicknesses to be maintained at about two to one as desired. The method includes depositing forming a write pole by constructing a mask which may include a bi-layer hard mask, and then ion milling to form the write pole. Once the write pole has been formed, a layer of alumina or some other non-magnetic material can be conformally deposited. A reactive ion mill (RIM) can be performed to open up the top of the write pole (remove the horizontally disposed portions of the alumina layer). Then, a second layer of alumina or some other non-magnetic material can be deposited, and the write pole can be plated. The thickness of the side shield gaps is defined by the sum of the final thicknesses of the first and second alumina layers, while the thickness of the first magnetic layer defines the thickness of the trailing shield gap.

    摘要: A method of manufacturing a write pole that prevents P2 pedestal consumption during ion milling removal of coil and pole seed layers. The write head can be constructed by forming a first pole and then forming a magnetic pedestal (P2) over the first pole. A protective layer of, for example, alumina is deposited over a portion of the pedestal in the pole tip region, leaving a portion of the pedestal uncovered in the flare region. A coil seed layer can then be deposited and a coil formed. When the coil seed layer is removed, such as by ion milling, the pole tip region of the pedestal is protected from the ion milling by the protective layer. Similarly, a top pole can be deposited by first depositing an electrically conductive, magnetic seed layer and then plating the top pole. When the top pole seed layer is removed by ion milling, the pole tip region of the pedestal is protected from removal by the protective layer.
