An apparatus for recording and/or reproducing information on an optically inscribable and readable disc-shaped record carrier with a previously formed track pattern containing a first track modulation, in order to obtain a clock signal, and a second track modulation formed by a radial wobble, in order to obtain a tracking signal. A reference signal for generating a tracking signal via synchronous detection is derived from the clock signal by frequency synthesis. |
