Summary:1. Field of the Invention An optical disk system comprises an optical disk device and control circuitry. The optical disk device stores user data and transfers an analog signal representing the user data to the control circuitry. The control circuitry sub-samples the analog signal to generate a sub-sampled signal. The control circuitry up-samples and re-times the sub-sampled signal using a control signal to generate an up-sampled and re-timed signal. A digital feedback loop in the control circuitry generates the control signal.
