摘要

An apparatus for optically reading a record carrier on which information is contained in tangentially extending tracks includes a directing system for making the scanning spot cooperate with the desired track. In order to enable a jump-wise displacement of the scanning spot from a track being followed to an adjacent track, a switching device is provided for supplying a suitable control signal to the directing system. The control signal is automatically adapted to varying track distances, so that a correct jump-wise displacement of the scanning spot is guaranteed.
