An optical disc (11 to 18) having sectors (3) each having a sector ID further comprises: a first area (4) having a first set of sectors (313-315) sequentially arranged on the disc (11 to 18) according to their respective IDs, a second area (5) having a second set of sectors (316-318) sequentially arranged on the disc (11 to 18) according to their respective IDs, the second area (5) being located after the first area (4) in respect of a disc scan direction (B) and having at least one sector ID which duplicates that of a sector in the first set of sectors, a start sector (33) located before the first area (4), and navigation data indicating to an optical disc reader, after having read the start sector (33), to displace its pickup reader device to a first target sector (316, 317, 352) having a sector ID of one of the sectors of the second area (5) or of a sector located after the second area (5), wherein the number of sectors between the start sector (33) and the first target sector is chosen such that the optical disc reader jumps from the start sector (33) to the first target sector using a cross track mode.
