Abstract

Un dispositivo de espejo pivotante para un aparato que explora pistas de información en un portador de información con ayuda de un haz de radiación, cuyo dispositivo comprende un espejo pivotante que es pivotable alrededor de al menos un eje de pivotamiento y que tiene una cara anterior reflectante de la radiación y, en el lado inverso, una cara posterior, y una disposición de apoyo de espejo pivotante que comprende un soporte de apoyo rígido que tiene un primer extremo situado cerca de la cara posterior del espejo pivotante y un segundo extremo que está alejado de la misma, y un apoyo elástico de material elastómero que está conectado tanto a la parte posterior del espejo pivotante como al soporte de apoyo, cuyo material rodea el primer extremo del soporte de apoyo y una parte del soporte de apoyo junto al primer extremo, caracterizado porque dicha parte del soporte de apoyo que está situada junto al primer extremo tiene una sección transversal en un plano perpendicular a dicho eje de pivotamiento que varía desde una dimensión transversal mínima en un primer extremo a una dimensión transversal máxima en un lugar situado más cerca del segundo extremo.
