  • Method and apparatus for generating tracking error signal and optical information storage system including the apparatus
    Patent number: 8861321
    Abstract: Provided are an apparatus and method of generating a tracking error signal, and an optical information storage system including the apparatus. The apparatus includes a bias signal generator for generating a bias signal for canceling a direct current (DC) offset of a push-pull signal using a tracking control signal generated by the tracking controller. Accordingly, an offset generated in a tracking error signal may be canceled or otherwise reduced using the bias single instead of using an additional side beam.
    Type: Grant
