PROBLEM TO BE SOLVED: To attain the accurate tracking operation also against the tracking error caused by large external disturbance. SOLUTION: The device is provided with a recording/reproducing part 3 for recording/reproducing data with respect to a disk-like recording medium 10, an eccentric amount storage part 6 for storing the eccentric amounts in the radial direction of a head 2 at each position in the circumferential direction of the disk-like recording medium 10, and a CPU 5 for executing the tracking servo control based on a tracking error signal and obtaining the eccentric amount of the head 2 of the disk-like recording medium 10 to store it in the eccentric amount storage part 6 when the tracking servo control is not being executed, then this method is realized by reading out the eccentric amount from the eccentric amount storage part 6 by the CPU 5 and executing the tracking servo control of the head 2 in accordance with this read out eccentric amount.
