ABSTRACT:
A magnetic tape of the present invention comprises a plurality of servo bands and servo signals for performing tracking-control of a magnetic head, wherein the servo signals are recorded on the servo bands, wherein a DC magnetization region magnetized in one direction by direct current is arranged along longitudinal directions of the magnetic tape on the servo bands, wherein each of the servo signals is magnetized in a reverse direction for the one direction of a DC magnetization and is recorded within the DC magnetization region, and wherein any of a relative ratio and relative difference of DC magnetization intensity in the DC magnetization region and recording magnetization intensity of each of the servo signals differs for each of the servo bands.
