Abstract:
A magnetic recording medium comprising:a substrate;a magnetic recording layer which is formed on said substrate and on which a plurality of tracks are set in a shape of concentric circles along a circumferential direction, said magnetic recording layer having a plurality of servo regions discontinuously disposed in the circumferential direction; anda plurality of tracking servo patterns formed in each of said plurality of servo regions, individual ones of said plurality of tracking servo patterns being continuously formed in at least one of a linear and curved manner so as to obliquely cross said plurality of tracks in each of said servo regions, and being discontinuously arranged such that:a first tracking servo pattern on a first track is shifted a predetermined amount to one side of the circumferential direction from a second tracking servo pattern on a second track adjacent to the first track;said second track servo pattern is shifted said predetermined amount to said one side of the circumferential direction from a third tracking servo pattern on a third track adjacent to the second track; andsubsequently in the same manner, an N-th tracking servo pattern on an N-th track is shifted said predetermined amount to said one side of the circumferential direction from an (N+1)-th tracking servo pattern on an (N+1)-th track adjacent to the N-th track.
