Original Abstract Submitted

According to one embodiment, a magnetic head includes a first magnetic pole, a second magnetic pole, and a magnetic element provided between the first and the second magnetic poles. The magnetic element includes first to fifth magnetic layers. A differential electric resistance of the magnetic element when a voltage between the first magnetic pole and the second magnetic pole being changed includes a first positive peak and a second positive peak. The voltage corresponding to the first positive peak is a first positive peak voltage. The voltage corresponding to the second positive peak is a second positive peak voltage. The second positive peak voltage is higher than the first positive peak voltage. An element voltage applied between the first magnetic pole and the second magnetic pole in a recording operation is higher than the second positive peak voltage.
