Abstract
La présente invention concerne une cassette vidéo (10) à bande sans fin. Cette cassette est relativement bon marché à fabriquer. Elle comporte une longueur de bande (40) sinueuse (A, B, C, A', B', C') relativement longue. Elle conserve suffisamment de tension (22, 24, 28) sur pratiquement toute la longueur de la bande lorsque la cassette est en utilisation ou en reproduction, mais de préférence aussi lorsque la cassette n'est pas en utilisation. Cette cassette garantit qu'il n'y a pratiquement aucun contact interbande et sensiblement aucun contact entre la bande et les surfaces statiques lors du défilement de la bande. L'invention concerne également des dispositifs (64-69) permettant d'utiliser une cassette vidéo à bande sans fin (10) pour la reproduction en continu de séquences audiovisuelles et/ou pour l'accès direct à des vues vidéo ou à d'autres unités de données stockées sur la bande (40), ou pour la recherche en temps réel de vues vidéo.
