ABSTRACT:
An optical disk device includes a pickup head configured to record and read data on and from an optical disk, and a recording/reproducing circuit such as a RF amplifier. The optical disk device also includes a control section configured to determine whether or not recording of data by the pickup head is normal and exercises control for predetermined instructions to be given to the pickup head based on the result of determination. If it is determined that the recording by the pickup head is erroneous, the control section carries out a control process such as to stop recording and then resume recording at a position moved a predetermined amount from an error position at which the pickup head has stopped recording.
