Abstract

Tête de lecture/écriture à coussin d'air pour supports d'enregistrement souples. La tête 5 comporte un corps 8 dont la face 12 en regard du support d'enregistrement souple est sphérique. L'élément de transduction 10 de la tête est entouré par une gorge circulaire 13 qui assure le maintien d'une hauteur de vol constante pour le support d'enregistrement, au moyen d'un coussin d'air entre la face 12 et ledit support d'enregistrement. Tête utilisable notamment pour la lecture/enregistrement de disques magnétiques souples.
