Land Pre-Pit data detection apparatus and method thereof |
摘要 |
An apparatus and method have capabilities of precisely detecting Land Pre-Pit (LPP) data recorded on an optical medium loaded into an optical drive. The apparatus includes an LPP data detecting unit that detects LPP data, from which a wobble frequency is removed, from a signal reflected from the optical medium; a wobble signal detector that detects a wobble signal from the reflected signal; and an LPP data generator that generates the LPP data recorded on the optical medium, using the detected LPP data and the detected wobble signal.
