Title (EN) DEBRIS CONTROL IN AN ENCLOSED MAGNETIC TAPE CARTRIDGE
(FR) DISPOSITIF ANTI-DEBRIS POUR CASSETTES A BANDE MAGNETIQUE
Abstract:
(EN) In order to diminish the effects of debris on recording and playback in a cartridge loaded recorder, adhesive material (28) is placed inside the enclosed magnetic tape cartridge (10). The adhesive is placed on appropriate interior walls and other available surfaces of the cartridge and is covered by a protective screen (27) having holes (29) through which the debris may pass. The size of the holes is large relative to the debris size. The adhesive material is located clear of the magnetic tape path, magnetic heads and guides and if an inadvertent tape loop occurs in the cartridge, the protective screen insures that the magnetic tape cannot come into contact with the adhesive proper. Any loose debris however incident on the holes of the protective screen is captured and immobilized by sticking to the adhesive material.
(FR) Pour réduire les débris qui peuvent affecter l'enregistrement et la reproduction dans les appareils d'enregistrement magnétique à cassettes, un matériau adhésif est disposé sur des parois intérieures et d'autres surfaces appropriées de la casette, ledit matériau étant protégé par un écran (27) caractérisé par des trous à travers lesquels peuvent passer les débris. Le matériau adhésif est disposé à l'écart de la trajectoire de la bande magnétique, des têtes magnétiques et des guides. Si une boucle devait se former accidentellement dans la cassette, l'écran protecteur empêcherait que la bande magnétique vienne en contact avec ledit matériau adhésif. Par contre tous débris passant par les trous de l'écran protecteur sont saisis et immobilisés par le matériau adhésif.
