Abstract

SOPORTE DE REGISTRO DE INFORMACION EN DISCO MAGNETICO.ESTA CONSTITUIDO POR UN DISCO MAGNETICO (3) Y UN ELEMENTO DE CASQUILLO (6) SITUADO CENTRICAMENTE EN EL DISCO Y QUE PRESENTA UN ORIFICIO (7) NO CIRCULAR, DESTINADO A RECIBIR UN EJE DE ACCIONAMIENTO CIRCULAR QUE SIRVE PARA HACER GIRAR EL DISCO MAGNETICO. EL CASQUILLO INCLUYE AL MENOS DOS SUPERFICIES DE REFERENCIA (8) QUE CONVERGEN LA UNA HACIA LA OTRA Y QUE FORMAN DOS PAREDES RESPECTIVAS DEL ORIFICIO, Y UNO O VARIOS ELEMENTOS ELASTICOS (9) QUE TIENEN UNA SUPERFICIE QUE FORMA UNA TERCERA PAREDDEL ORIGIFICIO. LAS TRES PAREDES ESTAN DISPUESTAS Y DIMENSIONADAS DE TAL MANERA QUE CUANDO UN EJE DE ACCIONAMIENTO CIRCULAR ESTA SITUADO EN EL ORIFICIO, LAS SUPERFICIES DE REFERENCIA Y LA SUPERFICIE DEL ELEMENTO FLEXIBLE ESTEN TODAS EN CONTACTO TANGENCIAL CON EL EJE DE ACCIONAMIENTO CON EL FIN DE QUE PUEDAN GIRAR AL SER ARRASTRADAS POR EL DURANTE LA ROTACION DE DICHO EJE.
