CA 2227170

A magnetic tag or marker is described which is capable of func- tioning as a multi-bit information carrying tag. The tag may be at- tached to an article and then used as a means of identifying that article, generally as it enters or is positioned within an interrogation zone. The tag comprises (a) a first magnetic material characterised by high permeability, low coercivity and a non-linear B-H characteristic; and (b) a second magnetic material which is capable of being per- manently magnetised, the second magnetic material being magnetised with a non-uniform field pattern (A, B, C). Detection systems for use with such tags, and write/read system using them, are also disclosed.

Marqueur ou étiquette magnétique pouvant fonctionner comme étiquette portant des informations à plusieurs bits. Cette étiquette peut être fixée à un article, puis utilisée comme moyen d'identification de cet article, généralement lorsqu'elle est introduite ou positionnée dans une zone d'interrogation. L'étiquette comprend (a) un premier matériau magnétique caractérisé par sa perméabilité élevée, une faible force coercitive et une caractéristique d'aimantation non linéaire; et (b) un second matériau magnétique susceptible de subir une aimantation permanente selon une configuration de champ non uniforme (A, B, C). Des systèmes de détection s'utilisant avec de telles étiquettes sont également décrits, ainsi que des systèmes d'écriture/lecture faisant appel à ces étiquettes.
