Abstract

L'invention est un dispositif d'entraînement de disques optiques servant de supports d'enregistrement. Ce dispositif comporte un mécanisme servant à commander l'inclinaison relative entre un disque optique et un objectif pour enregistrer des données et/ou lire des données enregistrées sur un premier disque optique à densité d'enregistrement standard et sur un second disque optique à grande densité d'enregistrement. L'inclinaison relative entre le second disque optique et l'objectif est commandée par le mécanisme de commande d'inclinaison seulement quand le second disque optique est chargé et que l'on procède à l'enregistrement de données et/ou à la lecture de données enregistrées sur le second disque optique.
