ABSTRACT:
The invention relates to devices for optically recording information on a rotating carrier with a recording spot along a track. In accordance with the present invention, there is provided a reading spot kept at a constant distance, equal to an integral multiple of the pitch of the track, from said recording spot. The reading spot is made to follow an already recorded track element by means of a feedback loop. The simultaneous displacement of the two spots is controlled by a signal obtained by the detection of the reading beam.
