The present invention relates to a method and a circuit for recovering information (INF) contained in a wobbled track (36) on an optical storage medium (34). One aim of the invention is to describe a method within an appliance for reading from and/or writing to optical storage media (34), whi ch can correct disturbing data signal components (AS') in the wobble signal (TW ) even when the swept frequency and the lowest signal frequency are close to o ne another. According to the invention, this object is achieved in that the signals (A+D,B+C) from two detector halves (1A+1D,1B+1C) of a photodetector (1) which is used for reading the data contained in a track (36) on an optic al storage medium (34) are provided with weighting factors (K1, K2) which are adjusted dynamically during operation of the appliance. In order to adjust t he weighting factors (K1, K2), the data signal component (AS') in the wobble signal (TW) is linked to a disturbance signal (DS) from a disturbance signal generator (12).
