The invention concerns a compact disc consisting of a support (210) treated on one surface for receiving a film for storing data arranged in the form of a circular ring (220) of digital data to be read by a compact disc player (100) comprising a removable drawer (110) provided in its base, a first circular cavity (120) having depth and diameter substantially greater than those of the disc so as to receive, position and wedge the selected disc. Said compact disc is characterised in that its support (210) adopts the shape of a rectangular calling card comprising a film for storing data in the form of a circular ring (220) whereof the outer circle is inscribed in said rectangle and means for positioning and wedging (230) said rectangular support in the drawer (110) of the player (100), and more particularly in the second circular cavity (130) designed to receive, position and wedge compact discs of smaller dimensions.

L'invention concerne un disque compact se composant d'un support (210) traité sur une face pour recevoir un revêtement de stockage d'informations organisées sous forme d'une couronne circulaire (220) de données numériques destinées à être lues par un lecteur de disque compact (100) du type de celui comportant un tiroir (110) extractable ménageant dans son fond une première excavation circulaire (120) de profondeur et de diamètre sensiblement supérieurs à ceux dudit disque afin de recevoir, de positionner et de caler ledit disque sélectionné. Ce disque compact est remarquable en ce que son support (210) adopte la forme d'une carte de visite de forme rectangulaire comportant d'une part, un revêtement de stockage d'informations en forme de couronne circulaire (220) dont le cercle externe est inscrit dans ledit rectangle et d'autre part, des moyens de positionnement et de calage (230) dudit support rectangulaire dans le tiroir (110) du lecteur (100) et plus particulièrement dans la deuxième excavation circulaire (130) destinée à recevoir, à positionner et à caler les disques compacts de dimensions moindres.
