Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA INSCRIBIR Y/O LEER UN DISCO (7) MAGNETO-OPTICO. EL DISPOSITIVO COMPRENDE: UN BASTIDOR (1) QUE LLEVA UNA PLATAFORMA GIRATORIA (5), QUE GIRA ALREDEDOR DE UN EJE DE ROTACION (11); UNA DESLIZADERA (17), QUE LLEVA UNA UNIDAD OPTICA (19); MEDIO (15) DE GUIA RECTILINEA, PARA LA DESLIZADERA SITUADA SOBRE EL BASTIDOR; Y UNA UNIDAD (25) DE ACCIONAMIENTO DE LA DESLIZADERA. EL DISPOSITIVO COMPRENDE ADEMAS: UN SUBBASTIDOR (3), QUE ESTA SUJETO AL BASTIDOR PARA QUE SEA MOVIL, Y OTRA DESLIZADERA (57) A LA CUAL, VISTA A LO LARGO DEL CITADO EJE DE ROTACION, SE SUJETA UNA UNIDAD (59) MAGNETICA, EN UNA POSICION OPUESTA A, Y DISTANCIA DE, LA UNIDAD OPTICA. EL SUBBASTIDOR LLEVA ADEMAS MEDIO DE GUIA RECTILINEA (55) PARA LA OTRA DESLIZADERA, CUYO OTRO MEDIO DE GUIA RECTILINEA SE EXTIENDE PARALELO AL MEDIO DE GUIA RECTILINEA PARA LA PRIMERA CITADA DESLIZADERA, AL MENOS DURANTE EL FUNCIONAMIENTO.-
