The invention relates to recordings in the form of disks and to the reading devices making it possible to repetitively read a still with its sound accompaniment. The invention relates to a recording where the video and audio data form interlaced blocks located in equal sectors of the same turn. The repetitive reading device utilizes buffer stores in which are loaded the video and audio data blocks. The reading of the buffer stores takes place at a reduced speed in order to reconstitute uninterrupted sequences of video and audio data. The invention is more particularly applicable to the storage of pictures on disk with their sound accompaniment with a view, for example, of giving programmed audio-visual instruction or teaching.
