Provided is a recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with at least data and, as a preamble necessary for controlling the reproduction of the data, a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction and synchronization patterns for synchronization processing, the synchronization patterns being recorded in front and rear of the separation pattern in a running direction of the plurality of tracks.
