An eccentricity suppression control method for suppressing an affect caused by an eccentricity of an optical disc and responding to the eccentricity of the optical disc quickly. In the method, eccentricity amounts according to a phase of the optical disc is detected and estimating correction amounts for each phase suitable for suppressing each of the eccentricity amount according to the phase. The estimating correction amount for each phase is added to a tracking control signal responding to a tracking error, thereby performing a tracking control quickly and accurately.
