Magnetic recording head with non-magnetic conductive structure
The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a trailing shield, a main pole, an STO disposed between the trailing shield and the main pole, and a non-magnetic conductive structure (or non-magnetic conductive layers) adjacent to the main pole and in contact with the STO. The non-magnetic conductive structure provides additional paths for electrical currents to flow to the STO. The non-magnetic conductive structure enables higher current density to the STO without creating hot spots at the MFS. Maximum current efficiency and uniformity can be achieved with the non-magnetic conductive structure.
