Abstract

The reader is of the type comprising at least one video disk with two faces and at least one reading (and recording) head arm which is movably mounted to scan the different possible faces, knowing that the essential interest of this type of readers is that it has a plurality of video disks. It is characterized in that it comprises at least two independent scanners (23-24, 25-25, and 27-28) which are so mounted that they may read both faces of each video disk A, B and C, either simultaneously or separately. A plurality of embodiments enables to adapt the invention to different practical necessities. In particular, it is possible to provide modular installations, by means of which a user may adapt the capacity of its installations to increasing needs. The possibility of reading (or recording) two faces of a same disk provides important advantages since it is then possible to have access within an extremely short time and "continuously" to a considerable number of data or information, and this has practical consequences particularly for exploiting banks of images or for the making of films.
