  • Patent number: 8824252
    Abstract: The invention discloses a signal clamping device capable of clamping a signal with a clamp level that is set according to a frequency characteristic of the signal and a method thereof and a related optical storage system. The signal clamping device includes an equalizing unit, a determining unit, and a clamping unit. The equalizing unit is utilized for equalizing the signal and generating an equalized signal. The determining unit is utilized for generating an indication signal according to the equalized signal. The clamping unit is utilized for determining a clamp level according to the indication signal and clamping the signal with the clamp level.

  • Publication number: 20060233075
    Abstract: Read focus error (FE) bias is calibrated on an embossed area of the optical disc. OPC is then performed with the calibrated servo signal bias to obtain a write power level. Data are written on and read from the optical disc based on the write power level and the calibrated servo signal bias.
