Classification: CPC G | IPC G

Claim 6:
7. 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
when an applied voltage applied between the first terminal and the second terminal while the recording current is supplied to the coil is higher than a first applied voltage, a frequency component of a signal obtained from the magnetic element includes a first frequency peak of a first frequency and a second frequency peak of a second frequency higher than the first frequency, and
when the applied voltage applied between the first terminal and the second terminal while the recording current is supplied to the coil is the element voltage, the frequency component includes the first frequency peak and does not include the second frequency peak, or a ratio of a height of the second frequency peak to a height of the first frequency peak is 0.1 or less.
