Abstract
1.Un dispositivo de brazo de soporte de cabeza para una pila de discos destinado a soportar una cabeza transductora en un extremo y destinado, en el otro extremo,a ser montado en un aparato posicionados de manera volada, comprendiendo el brazo una estructura de balancín relativamente rígida de sección transversal aplanada que define un plano a su través, cuya estructura es susceptible a resonancias fuera del plano, medios de amortiguación para amortiguar dichas resonancias, caracterizado porque: los medios amortiguadores comprenden una barra lateral relativamente rigida situada a lo largo de un borde longitudinal de la estructura de balancín, y una capa de material amortiguador relativamente elástico que proporciona una conexión mecanica entre la barra lateral y la estructura de balancín, con lo que las resonancias fuera del plano de la estructura de balancín son amortiguadoras por cizallamiento del material amortiguador como resultado del movimiento relativo entre el balancín y la barra lateral. 2.Un dispositivo de brazo según la reivindicación 1, en el cual los medios amortiguadores se extienden a lo largo de una parte, sólamente, de la longitud de la estructura de balancín junto al extremo del brazo que soporta la cabeza. 3. Un dispositivo de brazo según la reivindicación 1 ó 2, en el cual dichas barras laterales y capas respectivas de material amortiguador situadas a lados opuestos de la estructura de balancín. 4.Un dipositivo de brazo según cualquiera de las reivindicaciones precedentes, en el cual la orientación de la capa de material amortiguador, o de cada capa,es normal al plano de la estructura de balancín. 5. Un dispositivo de brazo según cualquiera de las reivindicaciones precedentes, en el cual la capa de material amortiguador es delgada en comparación con la barra lateral. 6. Un dispositivo de brazo según la reivindicación 5, en el cual la capa de material amortiguador, o cada capa, comprende una tira de cinta adhesiva de doble cara. 7. Un dispositivo de brazo según la reivindicación 6, en la cual, la cinta adhesiva de doble cara consiste en una membrana de refuerzo de poliester y el adhesivo es un material acrilico. 8. Un dispositivo de brazo según cualquiera de las reivindicaciones precedentes, en el cual tanto la estructura de balancín como la o cada barra lateral están hechas de aluminio. 9.Un dispositivo de brazo de soporte de cabeza para una pila de discos.
