Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE LECTURA DE CARACTERES (4) MAGNETIZABLES DISPUESTOS SOBRE UN SOPORTE (3). CONSTA DE UNA CABEZA DE LECTURA (1) PROVISTA DE MEDIOS DE IMANTACION (6) Y DE AL MENOS UN ELEMENTO MAGNETORRESISTIVO (5). CADA UNO DE LOS CARACTERES (4) PASA DURANTE EL DESPLAZAMIENTO RELATIVO DEL SOPORTE (3) EN RELACION CON LA CABEZA DE LECTURA (1) PRIMERO POR DELANTE DE LOS MEDIOS DE IMANTACION (6) Y LUEGO POR DELANTE DEL ELEMENTO MAGNETORRESISTIVO (5) Y DE UNA UNIDAD DE TRATAMIENTO ELECTRONICO (7). LA CABEZA DE LECTURA (1) TIENE UNA PLACA (15) DE MATERIAL FERROMAGNETICO COLOCADA JUNTO A LOS MEDIOS DE IMANTACION (6) QUE SE EXTIENDE HASTA LA PROXIMIDAD DEL ELEMENTO MAGNETORRESISTIVO (5); LA MENCIONADA PLACA (15) APLICA UN CAMPO MAGNETICO PERMANENTE Y HOMOGENEO AL ELEMENTO MAGNETORRESISTIVO (5).
