Abstract
An apparatus and method to detect an LPP sync signal on an optical storage medium include a frame sync bit detection unit detecting frame sync bits from the LPP sync signal on the optical storage medium and a sync detection unit determining whether continuity exists in the detection of the frame sync bits and detecting a 6-bit sector sync or a 3-bit sector sync using a 6-bit long window or a 3-bit long window, respectively, in response to a result of the determination. The apparatus further includes a sync detection result output unit outputting a sector sync detection period when continuity exists in the detection of frame sync bits and in the detection of the 3-bit sector sync or 6-bit sector sync and counting a sync detection signal and a new sync detection period when a sector sync signal is detected by the sync detection unit.
