摘要

There are provided an optical disc device having a wobble signal detection circuit, an information recording method, an optical disc device adjustment device, an adjustment method, a manufacturing method, a phase shift amount adjustment method, and an adjustment device. A wobble signal based on wobbling of an information track is input to the input side of a filter circuit and a phase difference between the input signal and the output signal of the HPF+LPF route at that time is detected. According to the phase difference detected, the phase of the recording start timing signal is adjusted, thereby preventing adverse affect of the phase shift in the filter circuit.
