PROBLEM TO BE SOLVED: To provide servo-position information encoded by magnetic polarity for a storage medium using magnetism as a base. SOLUTION: A magnetic storage medium includes a magnetic S-N servo band section and a magnetic N-S servo band section. The magnetic S-N servo band section includes a servo track segment, which is initialized by the polarity of the S magnetic pole, and a servo pattern of polarity of the N magnetic pole recorded on the servo track segment which is initialized by the polarity of the S magnetic pole. The magnetic N-S serve band section includes a servo track segment, which is initialized by the polarity of the N magnetic pole, and a servo pattern of the polarity of the S magnetic pole recorded on the servo track segment which is initialized by the polarity of the N magnetic pole. The magnetic S-N servo band section and the magnetic N-S servo band section are relatively recorded on the servo track, and, based on the servo pattern of the polarity of the N magnetic pole and the servo pattern of the polarity of the S magnetic pole, servo-position information encoded by the magnetic polarity is represented.
