An optical disc driving device employing an optical disc as a recording medium. The device includes a skew control mechanism for controlling relative tilt between an optical disc and an objective lens for selectively recording and/or reproducing data on or from a first optical disc having a standard recoding density and a second optical disc having a high recording density. The relative tilt between the second optical disc and the objective lens is controlled by the skew control mechanism only when the second optical disc is loaded and data is recorded and/or reproduced on or from the second optical disc.

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.
