Euhhh, oui, sur un disque qui tourne y aura des forces centrifuges... > euhhh peux > t'on m'expliquer ce que c'est ??? est ce qu'on déplace le polymer ???? > Bien sur! Les centres de rotation et de masse du CD ne seront jamais pile sur l'axe du lecteur. Avec les marges de fabrication, ca donne au CD qui vibre - cad une couche de polymer qui se deplace perpendiculairement a l'axe du CD. Les memes principes s'appliquent dans le plan parallele a l'axe du CD, avec en plus un Cd mince et flexible; et plus ca tourne vite, plus les forces centrifuges augmenteront les forces en jeu et le deplacement de la couche de polymer... *********************************************************************** This e-mail and its attachments are intended for the above named recipient(s) only and are confidential and may be privileged.
