Patent ID: 8098449

Claim:
A magnetic recording device comprising: a magnetic recording medium that includes 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 data; a reading unit configured to read out a signal from the magnetic recording medium; a write-clock generator configured to generate the write clock based on a write-reproduction signal which is a signal read out from the write-synchronization region by the reading unit; a phase-correction-value calculator configured to calculate a phase-correction value for correction of a phase of a read clock from the write clock based on a phase difference between the write-reproduction signal and a data-reproduction signal, which are read out by the reading unit; a correction-value-storage unit configured to store therein the phase-correction value calculated by the phase-correction-value calculator; a phase-correction unit configured to correct the phase of the write clock generated by the write-clock generator based on the phase-correction value stored in the correction-value-storage unit; and a data acquisition unit configured to acquire data included in a data-reproduction signal which is a signal read out from the data region by the reading unit based on a clock that is generated by correcting the phase by the phase-correction unit.
