On a magnetic recording medium, M sets of burst patterns are formed along
a direction of rotation of a substrate in each burst pattern region,
where M is a natural number of two or higher. Each burst pattern is
formed so as to include two types of burst signal units that are
positioned at different distances from a center of data track patterns
and have an equal length along a radial direction of the substrate. The
length along the radial direction is (2M/N) times the track pitch, where
N is a natural number of two or higher. In a predetermined range where
both ends in the radial direction do not match a center in the radial
direction of a burst pattern, (2M) centers in the radial direction of the
burst patterns are present at intervals of (1/N) times the track pitch in
the radial direction, the two types of burst signal units are formed of
non-recording regions and do not overlap each other in the direction of
rotation, centers of the burst signal units in the radial direction are
separated by (M/N) times the track pitch, and facing end parts in the
radial direction of the burst signal units are separated via recording
regions.
