Abstract
According to one embodiment, a magnetic head for reading data from a magnetic recording medium by utilizing a magnetic resonance phenomenon includes an auxiliary magnetic pole, a first oscillator, and a second oscillator. The auxiliary magnetic pole is to apply a magnetic field to the magnetic recording medium. The first oscillator is to oscillate at a first frequency and apply, to the magnetic recording medium, a first high-frequency magnetic field corresponding to the first frequency. The second oscillator to oscillate at a second frequency different from the first frequency and apply, to the magnetic recording medium, a second high-frequency magnetic field corresponding to the second frequency.
