Abstract

L'invention concerne un ensemble de support de têtes magnétiques. Il comprend un support piézo-électrique formé d'une lame bimorphe 30 montée en porte à faux à une extrémité et portant une tête magnétique à l'autre. Des couples d'électrodes 33, 39, 40 et 41 sont fixés sur ses surfaces principales opposées. Un circuit de commande applique entre les électrodes des différences de potentiel de même polarité, ce qui amène la déviation de la tête perpendiculairement au plan de l'élément de support au repos, ces différences de potentiel pouvant avoir des amplitudes différentes, si bien que la lame bimorphe subit une torsion faisant varier l'azimut de la tête magnétique qu'elle porte. L'invention s'applique aux magnétophones à balayage hélicoïdal et permet de réduire les erreurs de cadrage de pistes dans les modes d'avancement spéciaux.
