Abstract: An optical storage device and a blank detection method thereof are disclosed. An RF signal is obtained from an optical disc. A various gain amplifier amplifies the RF signal based on a control signal. An analog to digital converter samples the amplified RF signal to obtain a data signal. An auto gain controller updates the control signal based on amplitude of the data signal. A blank detector detects blankness of the data signal based on a threshold. The threshold is provided by a threshold generator based on the control signal. If the amplitude of the data signal does not exceed the threshold, the blank detector sends a hold signal to suspend update of the control signal.
