Abstract: The present disclosure generally relates to a magnetic recording head for magnetic media, such as a magnetic media drive. The head has a main pole, trailing shield, leading shield, first side shield, and second side shield. One side shield is electrically connected to the trailing shield and electrically disconnected from the leading shield. The other side shield is electrically connected to the leading shield and electrically disconnected from the trailing shield. The side shields are electrically connected through a hot seed layer and/or a nonmagnetic electrically conductive layer that is electrically disconnected from the main pole. Such an arrangement results in a current path from the trailing shield, through the side shields, around the main pole, and to the leading shield, which results in reduced resistance.
