Abstract

SE PRESENTA UN MARCADOR O ETIQUETA MAGNETICA QUE COMPRENDE A) UN PRIMER MATERIAL MAGNETICO QUE SE CARACTERIZA POR SU ALTA PERMEABILIDAD, SU BAJA COERCITIVIDAD Y UNA CARACTERISTICA B-H NO LINEAL; Y B) UN SEGUNDO MATERIAL MAGNETICO QUE ES CAPAZ DE SER PERMANENTEMENTE MAGNETIZADO, EL PRIMER Y EL SEGUNDO MATERIAL MAGNETICO SE SUPERPONEN ENTRE SI Y PREFERENTEMENTE COINCIDEN ENTRE SI. EL SEGUNDO MATERIAL MAGNETICO ES PREFERIBLEMENTE DE COERCITIVIDAD MEDIA. REGIONES SELECCIONADAS DEL SEGUNDO MATERIAL MAGNETICO PUEDE LLEVAR A CABO LA MAGNETIZACION DE FORMA QUE DIVIDAN MAGNETICAMENTE EL PRIMER MATERIAL MAGNETICO EN UNA SERIE DE ZONAS MAGNETICAMENTE DISCRETAS. LA LONGITUD DE LAS ZONA MAGNETICAMENTE DISCRETAS Y/O LAS LONGITUDES DE LAS REGIONES MAGNETIZADAS ("SEPARACIONES") DEL SEGUNDO MATERIAL MAGNETICO CONSTITUYEN LOS ELEMENTOS DE UN CODIGO.
