Abstract

According to one embodiment, a magnetic recording device includes a magnetic head and a controller. The magnetic head includes a first magnetic pole, a second magnetic pole, a magnetic element provided between the first magnetic pole and the second magnetic pole, a first terminal, a second terminal, and a coil. In the first operation, the controller is configured to supply a recording coil current to the coil while supplying a recording element current to the magnetic element. An absolute value of the recording coil current is equal to or less than the first coil current value.
