Title
(EN) MAGNETIC CODE COMPRISING A READING BASE AND READING SYSTEM THEREOF
(FR) CODE MAGNETIQUE COMPORTANT UNE BASE DE LECTURE ET SYSTEME DE LECTURE D'UN TEL CODE
Abstract
(EN) The invention concerns a magnetic code (1) and a reading system thereof, the code (1) comprising magnetic encoding elements (Ci) and magnetic reference elements (Bi) forming a code reading base (BA). The associated reading system comprises components with magnetoresistance for sensing the encoding elements and the code reference elements.
(FR) La présente invention concerne un code magnétique (1) et un système de lecture de ce code. Selon l'invention, le code (1) comprend des éléments magnétiques de codage (Ci) et des éléments magnétiques de référence (Bi) formant une base (BA) de lecture du code. Le système de lecture associé comprend des composants à magnétorésistance pour détecter les éléments de codage et les éléments de référence du code.
