    摘要： A method of fabricating a magnetic device is described. A mask removing layer is formed on a layered sensing stack and a hard mask layer is formed on the mask removing layer. A first reactive ion etch is performed with a non-oxygen-based chemistry to define the hard mask layer using an imaged layer formed on the hard mask layer as a mask. A second reactive ion etch is performed with an oxygen-based chemistry to define the mask removing stop layer using the defined hard mask layer as a mask. A third reactive ion etch is performed to define the layered sensing stack using the hard mask layer as a mask. The third reactive ion etch includes an etching chemistry that performs at a lower etching rate on the hard mask layer than on the layered sensing stack.

    摘要： In some examples, a system comprising a data storage member including a magnetic storage medium, the magnetic storage medium having a plurality of magnetic bit domains aligned on at least one data track, where a transition boundary between respective magnetic bit domains defines a transition curvature. The system may further comprise a magnetic read head including a first shield layer, a second shield layer, and a read sensor stack provided proximate to the first and second shield layers, where the magnetic read head senses a magnetic field of each of the plurality of magnetic bit domains according to a read playback sensitivity function. In some examples, the shield layers and read sensor stack may be configured to provide a reader playback sensitivity function that substantially corresponds to the shape of the respective magnetic bit domains.
