Abstract

Procédé de fabrication d'un corps en forme de plaque, et notamment d'un disque vidéo, par lequel la voiture circonférentielle dans la direction de l'épaisseur, les variations d'épaisseur et la déviation de la piste d'enregistrement sont réduites au minimum. Le procédé comprend les phases consistant à presser au moyen de moules une résine thermoplastique qui a été chauffée à une température supérieure à son point de ramollissement, et à refroidir la résine thermoplastique, la pression est abaissée à un bas niveau au moment où la résine thermoplastique a été refroidie à une température se situant aux alentours de son point de ramollissement. Ce faisant, on permet à la résine thermoplastique de se solidifier sans aucune tension résiduelle importante et locale, ce qui assure le minimum voulu de voilure circonférentielle, de variation d'épaisseur et de déviation de la piste d'enregistrement.
