This invention provides an optical disc device that can prevent the occurrence of an error in a starting position of a write operation due to off-tracking, and to avoid an unnecessary stop of the write operation during writing. A tracking error signal generator generates a tracking error signal from a signal which has been detected by an optical pickup, and a system controller detects off-tracking by comparing the tracking error signal with a threshold level, and turns control operation of a tracking servo controller off if the threshold level is exceeded. The off-tracking detection threshold level applied during a time period from completion of seek operation to a start of movement of the optical pickup to the starting position of the write operation is set to be lower than a threshold level applied during a time period of data recording.
