ABSTRACT:
An optical disk apparatus for detecting synchronization signals of an optical disk. Marks and spaces are alternately arranged as synchronization signals of the optical disk. An encoding/decoding circuit of the optical disk apparatus utilizes a rule for alternately arranging synchronization signals, thereby verifying a detected synchronization signal. When the polarity of a synchronization signal detected from a preceding synchronization frame is a mark, the next synchronization signal is a space. When the polarity of a detected synchronization signal is a space, the signal is determined to be a correct synchronization signal.
