Abstract

Structure de montage positionnable pour transducteur magnétique et système d'excitation y associé. Le transducteur est monté en bout d'une mince lame pour exploration latérale d'une piste enregistrée. Des portions de feuille inversement déformables maintiennent le transducteur en orientation normale par rapport à la surface d'enregistrement. La lame peut être un bimorphe avec éléments à polarisations opposées et câblages croisés pour inversion de déformation. Les électrodes des éléments peuvent être divisées longitudinalement et couplées à des tensions de polarisation pour correction d'erreurs d'azimut. Application particulière : magnétoscopes.
