PROBLEM TO BE SOLVED: To provide an optical disk recording/reproducing device which recognizes the position of a burst cutting region precisely. SOLUTION: The optical disk recording/reproducing device can move an optical pickup 2 in the radial direction of a rotating optical disk 1 to reproduce a signal from the optical disk 1 or to record the signal to the optical disk 1. Discrimination processing is repeated which fixes the optical pickup 2 at a fixed radial position of the optical disk 1 and detects the presence of a burst signal by a burst pulse discrimination circuit 9 for discriminating whether the position is the burst cutting region while the radial position of the optical pickup 2 is shifted. Thus, the position of the burst cutting region is detected. COPYRIGHT: (C)2008,JPO&INPIT
