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 mask forming method forms a concave/convex pattern in a mask when the mask is formed over a substrate. A coating film forming process forms a coating film by applying a radiation-curing coating composition onto the substrate. A radiation irradiating process then irradiates the coating film with radiation. Finally, a pattern transferring process presses a surface of a stamper on which a concave/convex pattern has been formed onto the coating film to transfer the concave/convex pattern to the coating film.
