Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for optimizing an area of switching synchronization component compression control, which can reduce correction errors between entire tracks in the same area, on the basis of a DC offset current value, if the number of areas of switching synchronization component compression control is fixed; and to provide a magnetic disc device. SOLUTION: The method for optimizing an area of switching synchronization component compression control corrects a positional error component in synchronization with the rotation of a disc, and includes a step of setting an area of switching synchronization component compression control whose number of area is fixed on the basis of the DC offset current value.
