Magnetic recording device, control device, and magnetic recording device control method

A magnetic recording device control method of controlling a magnetic recording device that includes a magnetic recording medium including a write-synchronization region on which information for generating a write clock is recorded, and a data region on which data is recorded, the write clock being a timing for writing the data, the control method comprising:

• allowing the a magnetic recording device to read out a signal from the magnetic recording medium;
• allowing the magnetic recording device to generate the write clock based on a write-reproduction signal which is a signal read out from the write-synchronization region in the reading-out of the signal;
• allowing the magnetic recording device to correct the phase of the write clock generated in the generating the write clock based on the phase-correction value stored in a correction-value-storage unit that stores therein the phase-correction value for correcting the phase of the write clock;
• and
• allowing the magnetic recording device to acquire data included in a data-reproduction signal which is a signal read out from the data region in the reading of the signal based on a clock that is generated by correcting the phase in the correcting the phase.
