Abstract
For the clock extraction from n digital signals read from each of n tracks there are provided n phase-locked loops. In order to compensate for speed variations in the speed of transport of the record carrier there is provided an additional frequency control system. This system derives a control signal which is a measure of the speed variations, which control signal is applied to the voltage-controlled oscillators of all the phase-locked loops as a common control signal.
