摘要： A magnetic recording apparatus includes a composite magnetic head which includes a recording head and a reproducing head; a magnetic storage medium; a discrete area; and a correction information recording area. Positioning correction information is able to be written in the correction information recording area at each track center. The apparatus also includes a center shift amount detection area. Center shift amount detection information is previously recorded in the center shift amount detection area. The center shift amount detection information is for measuring a center shift amount which indicates a relative distance between a tracking center and an actual track center of the discrete area when either the recording head or the reproducing head is positioned at a track center.
