Abstract
An apparatus for microwave-assisted magnetic recording includes a magnetic write head operable to write data to a magnetic storage medium. The apparatus includes a spin-torque microwave oscillator coupled to the magnetic write head and operable to provide microwave radiation to the magnetic storage medium. The apparatus includes a driver circuit in communication with the magnetic write head. The driver circuit is operable to dynamically modulate bias current provided to the spin-torque microwave oscillator in sympathy with data being written to the magnetic storage medium by the magnetic write head.
