Abstract
El dispositivo de registro de posiciones (2) contiene un mecanismo de generación de campo magnético (3)con al menos un polo magnético (4j), y unmecanismo sensor (5) con al menos un sensor (6) con un efecto magneto resistivo aumentado,en particular, un efecto magnetorresistivo gigante. Deacuerdo con la invención, el mecanismo generador de campo magnético (3) está dispuesto, con respecto al mecanismo sensor (5), de manera que la dirección deuna normal (H1) al plano de la capa de medición de al menos un sensor (6) tenga un ángulo distinto de cero con respecto a la línea de referenciaimaginaria (L1) sobre la que está ubicado a lo menos un polo magnético (4j), y el mecanismo generador de campo magnético (3) debe poderser desplazadorelativamente, con respecto al mecanismo sensor (5), de manera que se pueda registrar el campo magnético (h) de al menos un polo magnético (4j) de lacapa de medición de al menos un sensor (6), y que con ello se produzca un pasaje múltiple de la línea característica del sensor o de una parte de lamisma correspondiente a la cantidad de los polos magnéticos abarcados.
