The control circuit 10 calculates the resolution from the amplitude data 21. Correlation exists between the resolution of the magnetic recording medium and peak shift quantity, and since the peak shift quantity can be decided by deciding the resolution, the peak shift quantity can be decided based on a calculated result. Then, the peak shift quantity is written on the compensation quantity data write area 24 of the track as compensation quantity data 22 when the magnetic recording medium is initialized. In such a way, peak shift can be reduced in a small and inexpensive device.
