Method and apparatus for detecting saw-tooth wobble signal to reproduce information recorded on an optical disk |
摘要 |
An apparatus and method for detecting a STW signal to reproduce information recorded on an optical disk is provided. According to the method, a sine component is extracted from an input wobble signal containing a sine component and a cosine component, and the sine component is multiplied by a sine component having the same period as that of the sine component. After that, the multiplied results are accumulated and then a sign of the accumulated results is detected.
