Abstract

UNA MEMORIA OPTICA DE PLACAS PARA INFORMACION BINARIA ALMACENADA EN SERIE A LO LARGO DE UNA PISTA EN ESPIRAL CONO PICADO Y QUE PUEDE SER LEIDA POR MEDIO DE UN RAYO LASER DE ACUERDO CON EL PRINCIPIO DE INTERFERENCIA PUEDE SER MARCADA SIN LUGAR A ERROR EN UNA MANERA A PRUEBA DE FALSIFICACION PARA EL DISEÑADO DE UN NUMERO SELECCIONADO ENTRE LA TOTALIDAD DE DISPOSICIONES EN FORMA DE PRESIONES EN LA SUPERFICIE DE REFERENCIA OPTICA, QUE DISPONEN DE MENOS PROFUNDIDAD QUE EL PICADO. ESTE MARCADO, QUE PUEDE TOMAR CUALQUIER FORMA DESEADA PUEDE SER TAN PEQUEÑO QUE PUEDE SER UNICAMENTE VISIBLE POR MEDIOS MICROSCOPICOS ELECTRONICOS O TAN GRANDE QUE PUEDE SER RECONOCIDO CON EL OJO DESNUDO BAJO UNA LUZ DE MEZCLA.
