Abstract: PROBLEM TO BE SOLVED: To perform safe recording and reproducing operation by eliminate a focus-down and a track deviation phenomenon due to the passing of an obstacle and further shortening the time up to the recording and reproduction of a signal after the obstacle passage. SOLUTION: An amplifier means 15 generates a focus error signal 29, a tracking error signal, and an information signal 30 for the detection output of a pickup 4. An obstacle detecting means 16 detects whether or not there is an obstacle from the level of the signal 30 and informs a central processing means 21 of the detection result. An arithmetic means 18 performs state feedback compensating operation on the basis of the focus error signal 29 and an arithmetic means performs operation for an outer disturbance observer on the basis of the signal 29 to obtain a feedforward compensation signal. An adder 25 adds the compensation signal and an objective 8 is driven in the focusing direction through a D/A converter 26 and a driver 27 and positioned so that a track 2 is within the focus of the objective 8.
