A suspension assembly is described. The suspension assembly includes a load beam, the load beam includes a first set of spring extensions connecting a rigid region and a mounting region of the load beam. The suspension assembly also includes a base plate coupled to the mounting region of the load beam. The base plate includes two hinge members, each of the hinge members includes a second spring extension connected to the first set of spring extensions and coupling the load beam and the base plate. The base plate also includes a bender on a first side of the load beam connected to one of the two hinge members predisposing the rigid region to move from a first position to a second position.

A spin torque reversal assisted magnetic recording (STRAMR) structure is disclosed wherein a spin torque oscillator (STO) is formed in the write gap (WG) and generates one or both of a radio frequency (RF) field on a magnetic bit to lower the required write field during a write process, and a spin torque on a field generation layer (FGL) in the STO that flips a FGL magnetization to a direction opposing the WG field thereby increasing reluctance in the WG and causing larger write field output from the main pole (MP). The FGL is between two spin preserving layers that each conduct spin polarized current from an adjoining spin polarization (SP) layer. Current is applied from the MP and trailing shield to the SP layers, and returns to a direct current source through a lead from the FGL. STO sidewalls are self-aligned to a MP tip upper portion.
