Abstract
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.
