Abstract: Embodiments of the present disclosure generally relate to data storage devices, and more specifically, to a magnetic media drive employing a write head. The write head comprises a main pole and a monolithic side shield. A first leading shield is disposed below the side shield, and a second leading shield is disposed between the first leading shield and the side shield. The first leading shield has a greater throat height than a throat height of the second leading shield. A side shield throat height extending from the main pole to the side shield is shorter than the first leading shield throat height extending from the main pole to the first leading shield. The varying throat heights between the main pole, the side shield, and the first leading shield allow for enhanced cross-track recording density and reduce flux leakage from the main pole.
