Optimizing focus crosstalk cancelling

Method of setting a weight factor in a device for scanning an optical record carrier, the record carrier comprising a data layer having substantially parallel data tracks, the device comprising

• an optical head (22) comprising a detector for receiving radiation reflected from the data layer, the detector having main sub-detectors for detecting a main focus signal from a main spot and satellite sub-detectors for detecting a satellite signal from a satellite spot,
• focus control means (32) for providing a focus actuator signal to a focus actuator in dependence of a focus error signal, the focus control means comprising
• combining means (41) for generating the focus error signal based on the main focus signal and the satellite signal in dependence on a weight factor for adjusting a correction of the main focus signal by the satellite signal,
• filtering means (42) coupled to the focus error signal for generating the focus actuator signal,
• the method comprising the steps of
• setting the weight factor in dependence of an adjustment signal, and
• generating the adjustment signal based on the focus actuator signal.
