ABSTRACT:
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 (ZRP.sub.ij) which includes a group of preamble information (ZSY.sub.ij +ZSA.sub.ij), a group of absolute address information (ZAD.sub.ij), and a group of fine-position information (GDP.sub.ij). According to the invention, the mode of writing is characterized in that the preamble information group includes a first subgroup (ZSY.sub.ij) of synchronizing information preceding a second subgroup of automatic gain control (ZCA.sub.ij). The invention is applicable to magnetooptical memories.
