Magnetic recording head and magnetic recording apparatus

Abstract

It is made possible to improve the recording resolution. A magnetic recording head includes: a magnetic pole that has a first magnetic portion including an air bearing surface, and generates a write magnetic field; and a spin torque oscillator that is formed on the air bearing surface of the magnetic pole, and is formed with a stack structure including a first magnetic layer, a second magnetic layer, and a nonmagnetic layer interposed between the first magnetic layer and the second magnetic layer, the second magnetic layer generating a high-frequency magnetic field when current is applied between the first magnetic layer and the second magnetic layer.
