A method, apparatus, and system for implementing an integrated spin-torque oscillator (STO) with an interface bias control for hard disk drives. Bias circuitry 128 for a spin-torque oscillator 130 is integrated with a slider for microwave assisted magnetic recording (MAMR). The slider includes read and write transducers and the integrated STO bias circuitry controls a bias potential applied to a write return pole 134 of the write transducer with respect to a disk 126. The circuit may include an offset potential resistor 138. The STO may be coupled between a write pole the return pole. Control of the potential voltage of the slider can avoid corrosion, lube pickup, electric break down or electrostatic discharge to the disc. |
