ABSTRACT:
An apparatus for reading a record carrier in which information, for example video and/or audio information, is recorded in at least one track is described. By means of a detection system which comprises two radiation-sensitive detection elements which, viewed in the direction of length of the track, are arranged one behind the other so that they intercept two different parts of a radiation beam which has been modulated by the information of the track, positional errors of the plane of the track relative to a signal detection system can be detected.
