PROBLEM TO BE SOLVED: To suppress variation of an oscillating frequency of a spin torque oscillator even when the spin torque oscillator is set in the vicinity of a recording magnetic pole. SOLUTION: A magnetic head includes a recording magnetic pole 22, a spin torque oscillator 26 formed in the vicinity of the recording magnetic pole, and a magnetic field applying section 28 for applying the magnetic field to the spin torque oscillator. The magnetic field applied on the spin torque oscillator by the magnetic field applying section is practically perpendicular to the recording magnetic field generated by the recording magnetic pole.
