Abstract

L'invention concerne un système de dégagement d'un sillon de disque vidéo. Un bras à aiguille 130, 150 ayant un transducteur bimorphe 140 intégralement monté dessus est combiné avec un circuit électronique 22, 24 pour détecter des composantes prescrites du mouvement de l'aiguille et avec un circuit 27 pour appliquer un potentiel au transducteur pour permettre la correction du mouvement de translation au bras à aiguille. La présente invention s'applique aux systèmes de lecteur de disque vidéo.
