Abstract
A method for recording data on an optical disk, capable of detecting an abnormal state which may occur in the middle of data recording, preventing the abnormal state from damaging the optical disk, and recording data continuously from the position wherein the abnormal state happened after the abnormal state terminates. The method of the present invention comprises the steps of (a) examining if an abnormal recording state is encountered while recording data on the optical disk, (b) suspending data recording if an abnormal recording state is detected in step (a), (c) requesting retransmission of the data received in step (a) and receiving said data after said abnormal recording state terminates, and (d) recording said retransmitted data in a selected area on the optical disk.
