摘要：A microwave-assisted magnetic recording (MAMR) head according to one

embodiment includes a main magnetic pole adapted to generate a writing magnetic field

when current is applied to a write coil; a trailing shield positioned, at an air bearing

surface (ABS), in a trailing direction from the main magnetic pole; and a field generation

layer (FGL) positioned, at the ABS, between the main magnetic pole and the trailing

shield, wherein either a portion of the main magnetic pole closer to the FGL or a portion

of the trailing shield closer to the FGL is adapted to act as a spin polarization layer.
