Abstract
L'appareil comprend un moteur d'entrainement (20) ayant son stator (22) fixe par rapport au chassis et un rotor (26) à aimants permanents relié à l'axe d'entrainement (15) ainsi que des moyens permettant le déplacement axial du rotor (26) et de l'axe (15) d'une position de chargement du disque (12) dans laquelle le rotor est éloigné du stator, à une position de lecture du disque dans laquelle le rotor est près de et mis en rotation par le stator; le champ magnétique du moteur (20) étant utilisé pour déplacer le rotor (26) et l'axe (15) au moins partiellement entre ces positions.
