Each information recording track has pre-formatted fore and rear header sections containing address information identifying the track, which permit each of the recording tracks to be accessed from either of the header sections. A predetermined synchronization signal is pre-formatted in a storing area for each frame having a predetermined data size, so that information can be non-rewritably recorded onto the storing area for a predetermined frame by referring to the pre-formatted synchronization signal. With this arrangement, data can be recorded onto a selected information recording track in either of the directions of relative reciprocating movement of the recording medium to a recording/reproducing head, and thus the recording speed can be increased. The arrangement also allows data to be recorded even when one of the header sections has become unreadable due to some defect of the recording medium, and prevents occurrence of jitters in reproduced signals by allowing data to be recorded accurately at predetermined locations for each of the frames.
