In a magnetic disk device configured to perform tracking control on the magnetic head based on comparison output signals of different types of servo signals, in the servo sector, one frequency of the servo signals is applied to the scan start end side of the magnetic head. The magnetic head is characterized in that it has an index area in which an index signal consisting of a servo signal is recorded, and a comparison output signal of the two types of servo signals is obtained based on the index signal obtained through the magnetic head. disk device.
