THE PRESENT INVENTION RELATES TO A METHOD FOR THE DEMODULATION OF THE ADIP DATA (MONOTONE, REFERENCE, SYNC_0, SYNC_1, SYNC_2, SYNC_3, DATA_0, DATA_1) OF A WOBBLE SIGNAL (WOBBLE) OF AN OPTICAL RECORDING MEDIUM, WHEREBY THE WOBBLE SIGNAL (WOBBLE) 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 (FWOB) OF THE WOBBLE SIGNAL (WOBBLE); -DEMODULATING THE WOBBLE SIGNAL (WOBBLE) BASED ON THE RECOVERED CARRIER (FWOB); AND -PROVIDING A TWO-DIMENSIONAL MSK FILTER (5) FOR DETECTING MSK MARKS IN THE WOBBLE SIGNAL (WOBBLE)
