An apparatus for reproducing a wobble signal, including: a first filter unit receiving a wobble signal obtained by reading a wobble from a disc and passing a first band including a monotone frequency set according to the type or speed of the disc so as to generate a first wobble output signal; a second filter unit, when the wobble signal includes at least one frequency component, receiving the wobble signal and passing a second band including a multi-frequency set according to the speed of the disc so as to generate a second wobble output signal; and a wobble clock signal generation unit generating a wobble clock signal by quantizing one of the first and second wobble output signals. Accordingly, the wobble signal can be detected according to the type of disc, the speed of a disc, or a driving mode for the disc.
