When a recording condition judgement section (28) determines a recording condition of the recording of data onto a disk, and the recording is discontinued in response to the decision, a recording speed setting section (29) switches a recording speed to a speed one step slower than the previous recording speed. With this arrangement, when the recording condition is inferior, the recording is discontinued to thereby avoid a recording failure. Moreover, the recording speed is corrected stepwisely so that a disk adaptable recording speed can be set. Further, a recording start position at which to start additional writing is detected by the recording start position detection section (26), and the recording data is synchronized with the recording data by a synchronism setting section (27) to ensure successiveness before and after the recording data connection due to additional writing to the disk, before the recording is resumed.
