| titleOfInvention | Wobble signal extraction circuit and optical disk apparatus |
| abstract | A wobble signal is extracted from a first optical disk signal including a wobble signal component caused by wobble formed on the surface of the optical disk and a second optical disk signal including a wobble signal component having a phase opposite to that of the first optical disk signal. In the wobble signal extraction circuit, the signal level fixing unit (24a and 24b) fixes the first and second optical disc signals to a predetermined level when a non-continuous portion of the wobble is detected. |
