PURPOSE:To accurately detect a track deviation even when a signal from an adjacent track is mixed in an information signal since a track space becomes narrow to record information in high density. CONSTITUTION:This information recording medium is characterized by being provided with synchronizing signals Sa, Sb, Sc provided along tracks(a), (b), (c) on a disk surface by shifting the signals by a fixed position between adjacent tracks so that they may not overlap on a synchronizing signal in an adjacent track. |
