Title (EN) MAGNETIC PRINTING HEAD HAVING A HIGHT SIGNAL-TO-NOISE RATIO
(FR) TETE D'IMPRESSION MAGNETIQUE POSSEDANT UN RAPPORT SIGNAL/BRUIT ELEVE
Abstract: front page image
(EN)The signal-to-noise ratio as measured by the ratio of the full select magnetic field levels to the half select magnetic field levels, is improved in a coincident current magnetic printing head (Fig. 5, Fig. 6) by providing means (22, 13) for producing a bias magnetic field which is at least somewhat opposed to the signal magnetic fields.
(FR)Le rapport signal/bruit mesure par le rapport entre les niveaux de champ magnetique a selection pleine et les niveaux de champ magnetique a selection partielle, est ameliore dans une tete d'impression magnetique a courant coincidant en prevoyant des moyens (22, 13) de production d'un champ magnetique de polarisation qui est au moins quelque peu oppose au champ magnetique du signal.
