Abstract
According to an embodiment, a magnetic recording apparatus includes following elements. The spin torque oscillator generates a first oscillating magnetic field. The recording medium unit includes one or more recording medium layers which are stacked, each of the one or more recording medium layers including a recording medium and spin-wave lines each of which generates a second oscillating magnetic field. The write magnetic field source generates a write magnetic field. The controller is configured to control the spin torque oscillator, the spin-wave lines, and the write magnetic field source to simultaneously apply the write magnetic field, and the first and second oscillating magnetic fields to target medium magnetization in the recording medium.
