Abstract

Le tourne-disque vidéo est muni d'une plaque de stabilisation se trouvant pendant la lecture à faible distance au-dessus du disque, cas dans lequel de l'air peut traverser une restriction d'admission entre la plaque de stabilisation et le disque de façon qu'il se forme une dépression à cet endroit par suite de l'effet de pompage centrifuge du disque vidéo. Pour éviter l'entraînement par aspiration du disque pendant la montée de la plaque de stabilisation, un orifice de circulation d'air est prévu et peut être ouvert à l'aide de soupapes d'air après la lecture du disque en vue d'admettre un plus grand courant d'air entre la plaque de stabilisation et le disque vidéo en rotation pour éliminer, au moins en majeure partie, la dépression à cet endroit. Application : tourne-disque vidéo.
