    Abstract: A data search system for searching a data sync pattern stored in an optical disc by using a physical address is disclosed. The data search system comprises a physical address decoder, a data start indicator and a data sync pattern search circuit. The physical address decoder decodes a physical address signal read from the optical disc to obtain the physical address of a current position. The data start indicator generates a start search signal when the pickup head indicates a predetermined physical address to decide a start position. The data sync pattern search circuit searches the data sync pattern of the data from the start position to determine a cluster area of the data following the data sync pattern. The data search system further comprises a window generator, generating a window interval starting from the start position to search the data sync pattern therein.

    Abstract: Disclosed is a data search system for searching the data sync pattern by using a physical address or by detecting the falling edge of the blank area end. The data search system comprises a first data start indicator, a second data start indicator, a decision circuit, a window generator and a data sync pattern search circuit. The first data start indicator generates a first start search signal indicating a first start position. The second data start indicator generates a second start search signal indicating a second start position. The decision circuit selects to output one of the start search signals. The window generator generates a window interval starting from the start position. The data sync pattern search circuit searches a data sync pattern of the data in the window interval to determine the data following the data sync pattern.
