Apparatus for detecting and correcting wobble error and phase locked loop circuit using the same

摘要

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