ABSTRACT:
The present invention relates to an optical disc apparatus having a wobble signal detection circuit, an information recording method, adjustment apparatus and method for an optical disc apparatus, a fabrication method for an optical disc apparatus, and adjustment method and apparatus for a phase shift amount. In the present invention, a wobble signal based on wobbling of an information track is supplied to the input side of a filter circuit, and the current phase difference between input and output signals to/from an HPF+LPF path is detected. Then, the phase of a recording start timing signal is adjusted corresponding to the detected phase difference. As a result, it is possible to prevent adverse effect due to the phase difference in the filter circuit.
