Summary Detecting mis-tracking during recording (by watching the ADIP addresses).

Abstract A disk recording apparatus for recording data such as information concerning a musical performance on a recording disk (1) to which absolute addresses have been imparted in advance. Vibration during the recording operation and unexpected track jumping due to defects in the recording disk are detected relying upon the discontinuity of absolute addresses reproduced from the recording disk (1). In case track jumping has taken place, the laser power of the optical head (12) is dropped to the reproduction level and the track jump control is actuated to access a desired track. The recording operation is then resumed for the track.
