The present invention relates to a method for recovering land pre-pits from a signal obtained from an optical recording medium. According to the invention, the method comprises the steps of: generating a corrected wobble signal for rejecting wobble beats, providing a phase locked loop for the wobble signal for the accurate measurement of the phase of the land pre-pits, and providing a low-noise phase detector for the phase locked loop. <IMAGE>
