Abstract

L'invention concerne un plateau servant à maintenir et à porter de multiples têtes de lecteurs de disque dur. Sur la surface d'une section (12, 15) de positionnement, le plateau (10) comporte de fines protubérances aux endroits où sont fixées les têtes (30) de lecteurs de disque dur. Un exemple de fine protubérance est une protubérance (20) hémisphérique présentant une hauteur (quelques centaines de νm) un peu plus grande que l'épaisseur d'un conducteur (34) électrique. Un autre exemple est une protubérance (21) linéaire de plusieurs centaines de νm de largeur, et de plusieurs millimètres de longueur. Cet aménagement permet à la section de conducteurs électriques des têtes (30) de lecteurs de disque dur de toucher la section (12, 15) de positionnement du plateau (10) uniquement aux fines protubérances (20, 21), ce qui permet de réduire suffisamment les frottements entre celles-ci. Par conséquent, l'aménagement permet de prévenir des problèmes tels que des dommages occasionnés au conducteur (34) électrique et une coupure de celui-ci dus à des frottements.
