A mode of writing synchronization information on a magnetic recording carrier (DISC) where the information is written in binary code and distributed over a plurality N of tracks, each track being associated with at least one reference zone (ZRPij) which includes a group of preamble information (ZSYij+ZSAij), a group of absolute address information (ZADij), and a group of fine-position information (GDPij). According to the invention, the mode of writing is characterized in that the preamble information group includes a first subgroup (ZSYij) of synchronizing information preceding a second subgroup of automatic gain control (ZCAij). The invention is applicable to magnetooptical memories. |
