PROBLEM TO BE SOLVED: To make data recording performable while securing the continuity of recording data, even in the occurrence of an abnormality in a recording operation such as track-jumping. SOLUTION: This optical disk device is equipped with an optical head 3 for emitting a laser beam to an optical disk 2 rotatably driven by a spindle motor 1, a circuit 6 for performing the tracking control of this optical head 3, an abnormality detecting means 30 which is provided with a circuit 32 for detecting the generation of track-jumping based on a tracking error signal and with a circuit 33 for detecting discontinuity of recording data, a control circuit 7 for lowering the output of the optical head 3 when an abnormality of recording operation is detected by the means 30, and a memory 14 in which data writing is performed even in the detection of an abnormality of recording operation, and at the time of detection of an abnormality in recording operation by the detecting means 30 during the data recording, the device lowers the output of the optical head 3, returning to the starting end of the cluster where an abnormality is detected in the recording data, resuming the recording operation, and recording the data stored in the memory 14. |
