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.
