METHOD FOR REPRODUCING OPTICAL DISC SIGNAL, AND OPTICAL DISC DEVICE

摘要

An optical disc device is provided with means (116, 117) for generating a synchronization signal from a signal which is read from a wobble and has position information configured by a wobble groove; a timing correction circuit (127) for generating a control signal having a time width (TW) prescribed time after the synchronization signal is generated; and a DC level correcting means (126) for correcting a DC level of an information read signal through clamping with a time width of a control signal. After performing DC level correction by the DC level correcting means (126) to the information read signal close to a head of a recorded data region, the signal is reproduced by a binarizing means at a subsequent stage.
