An apparatus for detecting and correcting an error in a wobble signal and a phase locked loop (PLL) circuit using the apparatus. The apparatus includes a window generator (511) generating a window signal using a phase locked wobble signal, which is generated in synchronization with a raw wobble signal which is obtained by binarizing the wobble signal read from an optical recording medium, and a control operation unit (512) that corrects an error in the signal rwb and outputting the corrected rwb when the error in the signal rwb is detected in a window. Accordingly, an error in a wobble signal can be detected and corrected using a window signal, thereby increasing the performance of an optical recording/reproducing system.
