A Continuous Loop Magnetic tape Cartridge

Continuous magazine tape loops have application in educational and training devices, point-of-sale devices, home recording, display controls, industrial controls, telemetering, etc. Magazines, cartridges, and equipment designed to operate continuous magnetic tape loops present many engineering problems not usually encountered in standard two-reel techniques. Because the inside strand of the endless loop is pulled from the center and returned to the outside circumference of the tape mass, there is a resulting sliding action between each adjacent tape strand. Tape loops therefore require special handling devices and lubrication treatment to overcome malfunction and complete binding. The ultimate quality of electronic and mechanical performance of a continuous tape loop is comparable to standard tape performance. A continuous tape magazine has been designed to convert most standard tape machines to operate continuously. Also, a cartridge and mechanism has been developed to thread and play the tape automatically by simply inserting the cartridge.
