要約(英語): This paper proposes a control system for suppressing tracking error offset and multiharmonic disturbance in high speed optical disk systems. Residual tracking error consists of primary harmonics, high-order harmonics, and offset. Therefore, this paper proposes a tracking control system for suppressing residual tracking error, including primary harmonics, high order harmonics disturbance, and offset. The cause of the offset included in the residual tracking error is discussed. The cause is found to be the operation error in the fixed-point DSP (digital signal processor) and the phase lag of the LPF (low pass filter). Moreover, the proposed control system is designed for two types of high-speed optical disk system. The experimental results show that the proposed system enables an optical disk system to achieve a fine tracking performance.
