摘要：
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 is modulated using two different methods, 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 recovering the carrier of the wobble signal, demodulating the wobble signal based on the recovered carrier, and providing a two-dimensional MSK filter for detecting MSK marks in the wobble signal.
