| 摘要 |
<p>The present invention relates to a method for the demodulation of the ADIP data of a wobble signal of an optical recording medium, whereby the wobble signal comprises different types of wobble periods, and to an apparatus for reading from and/or writing to optical recording media using such method. According to the invention, the method comprises the steps of transforming the frequency and/or phase of harmonic deviations within the wobble signal to amplitude deviations, detecting the amplitude deviations, and detecting a current type of wobble period from the detected amplitude deviations. <IMAGE></p> |
