An apparatus (C) manufactures an information record medium (DK), which has a track (G, L), on which information is optically recorded. The apparatus is provided with: a track forming device (40, 43, 50) for forming the track; and a transition portion forming device (40, 43, 50) for forming a transition portion (MG) for transiting an irradiation position (SP) of a light beam (LG, LL), which is used for illegally copying the information on the formed track, from an irradiation track (G2), which is irradiated by the light beam, to an adjacent track (G1), which is adjacent to the irradiation track and on which the information is recorded before the information is recorded on the irradiation track, such that the formed transition portion is continuous with the formed track.
