Abstract

LA INVENCION SE REFIERE A UN EQUIPO PARA UN MEDIO DE MEMORIA OPTICO CON FORMA DE DISCO. EL MEDIO DE MEMORIA INTRODUCIDO PUEDE DESPLAZARSE POR LO MENOS EN UNA DIRECCION PERPENDICULAR A UN EJE DE GIRO PARA ALCANZAR UNA POSICION DE TRABAJO EN LA ZONA DE ACCION DE UN DISPOSITIVO EXPLORADOR OPTICO. PARA DERIVAR UNA SEÑAL CUANDO EL MEDIO DE MEMORIA SE ENCUENTRA EN UNA POSICION INTERMEDIA, HAY POR LO MENOS UNA BARRERA OPTICA DE REFLEXION EN EL MISMO LADO DEL MEDIO DE MEMORIA QUE EL DISPOSITIVO EXPLORADOR.
