ABSTRACT:
An optical storage system includes an optical pickup unit movable across an optical medium. The optical pickup unit has a light detector, a laser diode, and a laser driver signal processor circuit. The laser driver signal processor circuit includes a detected signal processing block for outputting read signals corresponding to light received at the light detector, and a read signal processing block for processing the read signals and generating control signals or synthesis signals according to the read signals. A control unit is coupled to the optical pickup unit for controlling the optical pickup unit and decoding data recovered from the optical medium.
