<p>A disc recording apparatus for recording data such as information concerning musical performance on a recording disc (1) to which absolute addresses have been imparted in advance. Vibration during the recording operation and unexpected track jump due to defect in the recording disc are detected relying upon the discontinuity of absolute addresses reproduced from the recording disc (1). In case the 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 effected to give access to a desired track. The recording operation is then resumed for the track.</p> |
