Abstract
An optical storage system includes an optical pick-up head for receiving and transforming an optical signal into an electric signal; a pre-amplifier for receiving the electric signal and outputting a RF signal and a position error signal; a data and timing recovery unit for receiving the RF signal and generating a modulated signal and a clock signal; an error correction unit for generating a data signal according to the modulation signal and the clock signal; a defect signal generator for receiving the RF signal and generating a defect signal according to the RF signal, wherein the defect signal is enabled when the RF signal has a defect; and an error correction controller for receiving the defect signal and generating an error correction control signal according to the defect signal, wherein the error correction unit further receives the error correction control signal and adjusts the decoding strategy of the error correction unit according to the error correction control signal.
