A data storage device is disclosed comprising a storage medium and a head configured to access the storage medium, wherein the head comprises a first write assist element (WA1) comprising a first terminal and a second terminal and a second write assist element (WA2) comprising a first terminal and a second terminal. The second terminal of the WA1 and the second terminal of the WA2 are coupled together to form a common node. A first bias signal is applied to the first terminal of the WA1, a second bias signal is applied to the first terminal of the WA2, and a common mode voltage is applied to the common node.

The present disclosure generally relates to magnetic recording devices with stable magnetization. The magnetic recording device comprises a lower leading shield, an upper leading shield disposed on the lower leading shield, a main pole disposed above the upper leading shield, a trailing shield disposed above the main pole and upper leading shield, and an upper return pole disposed above the trailing shield. A first non-magnetic layer is disposed between the lower leading shield and the upper leading shield, and a second non-magnetic layer is disposed between the trailing shield and the upper return pole. The lower leading shield has a different domain state than the upper leading shield, and the trailing shield and the upper leading shield have a same domain state. The materials and thickness of the first and second non-magnetic layers result in magnetostatic coupling or anti-ferromagnetic coupling.

A PMR (perpendicular magnetic recording) write head configured for microwave assisted magnetic recording (MAMR) includes a spin-torque oscillator (STO) and trailing shield formed of high moment magnetic material (HMTS). By patterning the STO and the HMTS in a simultaneous process the HMTS and the STO layer are precisely aligned and have very similar cross-track widths. In addition, the write gap at an off-center location has a thickness that is independent from its center-track thickness and the write gap total width can have a flexible range whose minimum value is the same width as the STO width.

A method in one embodiment includes fabricating a tape having an applicator portion for applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials. The method also includes applying the organic coating to the applicator portion of the tape, the organic coating being for coating a tape bearing surface of the magnetic head with the organic coating upon the applicator portion being run over the tape bearing surface of the magnetic head. The method further includes applying a lubricant to a data portion of the tape.
