摘要： 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 (2·M/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, (2·M) 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.

摘要： A magnetic recording medium constructed as a discrete track-type medium. The magnetic recording medium is constructed so that a track width of data recording tracks is equal to or smaller than a width produced by subtracting twice an off-track width of a magnetic head with respect to the data recording tracks during a recording of the recording data from a magnetic effective recording head width of the magnetic head. The track width is equal to or smaller than a width produced by subtracting twice an off-track width of the magnetic head with respect to the data recording tracks during a reproduction of the recording data from a magnetic effective reproduction head width of the magnetic head. A combined width of the track width and twice a width of the non-magnetic parts is equal to or larger than a combined width of the effective recording head width and twice the off-track width during the recording, and is equal to or larger than a combined width of the effective reproduction head width and twice the off-track width during the reproduction.
