A recording/reproducing method and apparatus that is capable of driving a recording medium of land/groove recording system using a wobbling signal without a land/groove identification information. The method and apparatus detects the wobbling signal from a recording medium having wobbled land and groove tracks and then multiplies a frequency of the wobbling signal. In the method and apparatus, various control are performed on a basis of a period and a phase of the multiplied wobble signal, so that it becomes unnecessary to switch the polarity of the wobbling signal for the land/groove identification.
