Abstract

Una disposición de espejo pivotante eléctricamente controlable, adecuada para uso en un aparato para leer ópticamente pistas de información de un portador de información con ayuda de un haz de radiación, o para inscribir pistas de información sobre un portador de información, más en particular adecuada para uso en un reproductor de discos de video que opera por lectura óptica, y que comprende: un bastidor; un espejo pivotante con un frente reflectante y con un dorso; medios magnéticos permanentes que están rígidamente montados en el dorso del espejo pivotante para producir un campo magnético permanente para el control eléctrico del espejo pivotante; y un soporte de espejo para soportar de forma pivotable el espejo pivotante y que comprende un soporte de cojinete que está conectado al bastidor y un cojinete de espejo que está dispuesto entre el soporte de cojinete y el dorso del espejo pivotante, caracterizada porque entre el espejo pivotante y los medios magnéticos permanentes está interpuesta una placa de montaje que en su lado que mira hacia el espejo pivotante está provista de medios para situar el espejo pivotante y que en su otro lado está provista de medios para situar los medios magnéticos permanentes.
