Abstract
A magnetic recording head for microwave-assisted magnetic recording is disclosed. In one embodiment, a magnetic recording head is for applying a magnetic field from a main pole of said magnetic recording head for recording data to a disk. Further comprising a spin torque oscillator adjacent to said magnetic recording head and is for generating a high-frequency magnetic field at a stable frequency and amplitude. Further comprising a capacitor connected to an upper electrode of said spin torque oscillator via a first resistor and a lower electrode of said spin torque oscillator via a second resistor.
