Abstract
Dispositivo de transducción magnética de detección de informaciones magnéticas codificadas que comprende al menos un elemento magnético-resistente de detección de las informaciones dispuesto sobre un sustrato aislante, desfilando las informaciones por delante de este elemento, paralelamente a su superficie, caracterizado porque comprende un elemento magneto-resistente de compensación, dispuesto en la proximidad del elemento magneto- resistente de detección, de tal modo que no sea sometido al campo magnético de fuga de dichas informaciones y sea sometido a los mismos campos magnéticos parásitos que el elemento de detección siendo iguales las tensiones de las señales eléctricas de salida suministrada por los elementos de detección y de compensación en respuesta a la acción de los campos magnéticos parásitos sobre los mismos.
