Title (EN) CARTRIDGE TAPE SYSTEM FOR HELICAL SCAN TRANSPORTS
(FR) SYSTEME DE CARTOUCHE DE BANDE POUR MECANISME D'ENTRAINEMENT PERMETTANT LE BALAYAGE HELICOIDAL
Abstract:
(EN) This system makes use of a tape cassette helical scan tape transport (415-421) and 3480-type magnetic tape cartridge (401) as the data storage media. The merging of these two incompatible elements is accomplished by the use of a novel interface that implements a 'virtual tape cassette' using a tape cartridge (401) in a manner that makes this media compatible with the tape transport (415-421). The virtual tape cassette is implemented by providing a takeup reel (402) positioned with the magnetic tape cartridge (401) in a relationship that substantially matches the format of a magnetic tape cassette. A short tape threading arm (403) is used to retrieve the leader block (311) from the tape cartridge (401) and thread the magnetic tape (424) over a short tape threading path (423) to the takeup reel (402). Once the tape (424) is affixed to the takeup reel (402), the helical scan tape guide arms (415, 419) transport the length of tape (424) that is now exposed between the tape cartridge (401) and the takeup reel (402) to the rotary heads (416).
(FR) Ce système utilise un mécanisme d'entraînement permettant le balayage hélicoïdal pour cassette de bande magnétique (415-421) et une cartouche de bande magnétique de type 3480 (401) en tant que support de stockage de données. La combinaison de ces deux éléments incompatibles est effectuée grâce à l'utilisation d'une nouvelle interface qui met en ÷uvre une 'cassette virtuelle de bande magnétique' utilisant une cartouche de bande (401) d'une manière qui rend ce support compatible avec le mécanisme d'entraînement de la bande (415-421). La cassette virtuelle de bande magnétique est réalisée au moyen d'une bobine réceptrice (402) placée par rapport à la cartouche de bande magnétique (401) dans une position adaptée au format d'une cassette de bande magnétique. Un bras court de mise en place de la bande (403) est utilisé pour récupérer le bloc conducteur (311) de la cartouche de bande (401) et mettre en place la bande magnétique (424) sur la bobine réceptrice (402) en suivant un itinéraire court (423) de mise en place de la bande. Une fois la bande (424) fixée à la bobine réceptrice (402), les bras de guidage (415, 419) de la bande à balayage hélicoïdal entraînent la longueur de bande (424) qui est maintenant exposée aux têtes rotatives (416) entre la cartouche de bande (401) et la bobine réceptrice (402).
