Abstract
Mécanisme à bande pour enregistrer une information sur ou la restituer à partir d'une bande d'enregistrement, ledit mécanisme possédant des moyens d'entraînement répondant au contact avec lesdites bandes pour faire avancer ladite bande dans un sens donné, un transducteur pour permettre l'enregistrement ou la restitution de l'information acoustique en réponse au contact avec ladite bande pendant son passage devant lui, et des moyens pour contraindre ladite bande en contact avec lesdits moyens d'entraînement et ledit transducteur. Lesdits moyens d'entraînement et ledit transducteur sont associés en relation contiguë avec une surface de ladite bande, leurs zones respectives de contact avec ladite bande en une disposition côte à côte sensiblement latérale par rapport audit sens donné, de façon à ainsi réduire les vibrations dans ledit mécanisme. Application au cinéma sonore
