<p>A microwave-assisted magnetic recording head includes: a main magnetic pole that generates a recording magnetic field to be recorded on a magnetic recording medium; a shield; and an oscillator that is provided between the main magnetic pole and the shield and generates a microwave magnetic field. The microwave-assisted magnetic recording head is provided with a thermal expansion device for adjusting a relative position between the oscillator and the main magnetic pole so as to be able to independently adjust a recording magnetic field from the main magnetic pole and a microwave magnetic field from the oscillator.</p> |
