摘要： A track jump control device by means of which a scanning head for scanning the recording track of the disc-shaped recording medium is moved to a target track position is disclosed. A signal obtained by differentiating a tracking error signal is used as speed data to perform a closed loop track jump control operation to achieve direct landing on the target track positively even under an environment highly susceptive to disturbances. The track jump control making use of the gray code information indicating the recording tracks on the disc-shaped recording medium on the track-by-track basis is switched to the track jump control making use of the differentiated tracking error signal or vice versa to realize direct landing on the target track quickly and positively by a simplified arrangement.

In a region at the inside of an optical disk where the rotational speed of the spindle motor reaches its limit, a CAV mode is used for access, while in a region at the outside of the optical disk where a frequency band of an RF signal processor reaches its limit, a CLV mode is used for access. High-speed access to a maximum extent in a range of performance limits of the spindle motor and the RF signal processor is achieved. A retry feature retries failed access attempts to the optical disk when access failure is determined and a controller judges whether or not a defect of the optical disk has caused the access failure. The controller further judges if the predetermined cause of the access failure repeatedly occurs in a predetermined nearby range on the optical disk.
