Magnetic recording device and method for controlling magnetic recording device

A magnetic recording device, comprising:

• a magnetic recording medium;
• a magnetic head configured to record information on the magnetic recording medium;
• and
• a controller configured to control the magnetic recording medium and the magnetic head,
• the magnetic head including:
• a coil;
• a first magnetic pole configured to generate a magnetic field according to a recording current supplied to the coil;
• and
• a light emitting portion configured to irradiate the magnetic recording medium with light to locally increase a temperature of the magnetic recording medium,
• the controller being configured to perform a first operation and a second operation,
• in the first operation, the controller being configured to supply a first current to the light emitting portion to emit a first light to cause the first magnetic pole to record information on the magnetic recording medium, and
• in the second operation, the controller being configured to supply a second current to the light emitting portion to emit a second light to change a state of a contaminated member attached to the magnetic head, and
• the second current being greater than the first current.
