Abstract:
A magnetic recording head includes a trailing shield, a main pole, and a spin Hall layer. The spin Hall layer is disposed between the trailing shield and the main pole. A first spin torque layer is disposed between the spin Hall layer and the trailing shield. A second spin torque layer is disposed between the spin Hall layer and the main pole.
