Classification: CPC G | IPC G

Claim 7:
8. A magnetic recording device, comprising:
a magnetic head including
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 electrically connected to one end of the magnetic element,
a second terminal electrically connected to another end of the magnetic element,
a coil; and

a controller electrically connected to the magnetic element and the coil,
the controller being configured to perform a recording operation,
in the recording operation, the controller being configured to supply a recording current to the coil while applying an element voltage between the first terminal and the second terminal,
wherein
a differential resistance of the magnetic element when an applied voltage applied between the first terminal and the second terminal is changed while the recording current is supplied to the coil becomes a first differential resistance peak when the applied voltage is a first voltage, and
the element voltage is higher than the first voltage and less than 5.4 times the first voltage.
