Abstract

Un dispositif à disque procède au positionnement de chaque pince (222C) à une position prédéterminée en procédant au positionnement d'une plaque tournante avant de démarrer une opération de chargement de disque. Une position de transport d'un disque par un moyen de transport peut être considérablement décalée d'une position correcte uniquement dans un sens prédéterminé en fonction de la précision dimensionnelle des composants du dispositif à disque ou d'un disque, mais, même dans un tel cas, le volume de roulement d'un disque peut être rendu sensiblement constant à chaque occasion de tenir un disque en procédant au positionnement de chaque pince (222C) à une position correcte en fonction du sens de décalage. Par conséquent, la survenue d'un problème peut être réduite au minimum lorsqu'un disque est tenu au moyen de trois pinces (222C).
