Abstract
L'invention concerne un ensemble de support de tête magnétique. Il comprend un élément piézoélectrique 32 conçu pour effectuer un fléchissement en réponse à l'application d'une tension, une tête magnétique 31 montée sur une extrémité de l'élément 32, et un moyen d'application de tension à l'élément 32. Il comporte également un support 33 en forme de U destiné à l'élément 32, ce support étant fait en un matériau élastique et possédant deux branches 33b et 33c dont les extrémités libres sont élastiquement poussées l'une vers l'autre, l'extrémité de l'élément piézoélectrique qui est opposée à la tête magnétique étant placée entre les extrémités libres des branches du support ; la tête magnétique 31 est destinée à faire saillie par une ouverture 33c ménagée dans la partie réunissant les branches. L'ensemble de support de tête magnétique est par exemple destiné à être monté sur le tambour porte-têtes rotatif d un magnétoscope.
