发明名称 APPARATUS FOR READING A RECORD CARRIER
摘要 An apparatus for reading a record carrier (R) on which digital information (I) and tracking signals (S) of comparatively low frequency have been recorded. The apparatus comprises a correction circuit (14) to which the regenerated digital signal is applied, which correction circuit (14) has a transfer characteristic which at least within the frequency band of the tracking signals (S) corresponds to the transfer characteristic of the chain comprising the recording element (K), the record carrier (R) and the read element (K). The correction signal supplied by the correction circuit (14) is subtracted from the signal read and the tracking signals are derived from the signal thus obtained. In this way cross-talk components produced in the tracking signals by the digital signal are compensated for.
