Abstract
An optimum method for adjusting the physical position or angle of an optical pickup (a1) is automatically selected for each optical disc signal processing device so that a control target value after adjusted is included in a previous margin measurement result which is stored in a nonvolatile memory, thereby providing an optical disc signal processing device, an optical disc signal processing method, an optical disc reproduction and recording device, and an optical disc reproduction and recording method, which can reduce the start-up time and the recording start time, and enhance the user's convenience.
