A signal processing method and an optical pickup are capable of reducing signal distortion. Before being transmitted over a flexible cable to an optical disk drive controller, a low-pass filtering process is performed over the light detection signals or their arithmetic results in the optical pickup to eliminate high frequency compositions of the signals. By this way, the interference resulting from the flexible cable during signal transmission is mitigated. The retained data in the signals are further applied to recover servo control signals. Therefore, the stability of an optical disk servo control is improved, especially for a high-speed optical disk system.
