Abstract

"ETIQUETA MAGNETICA E MéTODO PARA CODIFICARDADOS EM UMA ETIQUETA MAGNéTICA". Compreendendo (a)um primeiro material magnético caracterizado por altapermeabilidade, baixa coercividade e um característica de B-Hnão-linear; e (b) um segundo material magnético capaz de serpermanentemente magnetizado, os citados primeiro e segundomateriais estando sobrepostos um sobre o outro e vantajosamenteterem substancialmente terminações comuns. O segundo materialmagnético é preferivelmente de média coercividade. As regiõesselecionadas do citado segundo material magnético podemcarregar magnetização de modo a magneticamente dividir oprimeiro material magnético em zonas discretas magneticamente, ocomprimento das citadas zonas discretas magneticamente e/ou oscomprimentos das citadas regiões magnetizadas ("intervalos")constituindo elementos de um código.
