Abstract

Dispositif lisant grâce à un capteur de ligne (10) les données contenues par des sous-pistes Ts, enregistrées optiquement sur une carte (1) dans laquelle une piste principale TM, composée d'une pluralité de sous-pistes Ts parallèles entre elles, est formée dans le sens de la longueur du substrat de la carte (1A), et dans laquelle chaque sous-piste Ts se compose d'une pluralité de points optiques. Des marques d'adresse t correspondant aux sous-pistes Ts sont formées le long du bord de la piste principale TM de la carte 1 et sont détectées par un détecteur optique (11). Les signaux de détection de marque sont ensuite comptés par un compteur d'adresses (12) pour détecter la position des sous-pistes Ts. En fonction de la valeur du compteur d'adresses (12), le mouvement relatif est commandé dans le sens de la piste principale parmi le capteur de ligne (10), le détecteur optique (11) et la carte (1). Grâce à cette invention, il est possible de lire sélectivement les données enregistrées dans l'une quelconque des sous-pistes Ts de la carte à enregistrement optique (1).
