OPTICAL DISC SIGNAL PROCESSING DEVICE, OPTICAL DISC SIGNAL PROCESSING METHOD, OPTICAL DISC REPRODUCING AND RECORDING DEVICE AND OPTICAL DISC REPRODUCING AND RECORDING METHOD

摘要

It is an object to provide an optical disc signal processing device, an optical disc signal processing method, an optical disc reproducing and recording device, and an optical disc reproducing and recording method that automatically select an optimum adjusting method of a physical position or an angle of an optical pickup (a1) for every optical disc signal processing device to make a control target value after the adjustment contained in past margin measurement results that are stored at a non volatile memory, so that they can be configured to shorten starting-up time or recording start time and to improve user's operational conveniences.
