Abstract

Dispositif de conversion magnétique comportant un élément à magnétorésistance. Dans le but de pouvoir utiliser un élément à magnétorésistance qui allie une hauteur élevée (et de ce fait une résistance convenable à l'usure) à une reproduction convenable de signaux à courte longueur d'onde, la résistance de l'élément est mesurée à l'aide d'un courant alternatif dont laMagnetic conversion device comprising a magnetoresistance element. In order to be able to use a magnetoresistance element which combines high height (and hence suitable wear resistance) with suitable reproduction of short wavelength signals, the resistance of the element is measured at using an alternating current whose
