Abstract

The present embodiments relate to a pre-assisting microwave assisted magnetic recording (MAMR) (PA-MAMR) write-head structure where the STO is disposed within a leading shield (LS). The STO can be used to pump energy into the media before the writing process. The STO can also pre-excite the media and let the media oscillation damp over the time and then switch under the writer field. The present embodiments can be easier to increase the magnetic volume and magnetic moment of the free layer, while also achieving a greater oscillation frequency with magnetization oscillations around the axis in the film plane.
