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.
