Magnetic Belt Cartridge for Recording/Reproducing Machines

The magnetic belt cartridge (cassette) provides a high-capacity magnetic recording, for example, one hour, in a compact form, that is easy to handle, and pack-feedable. The protected belt is transported by a single roller feed, with the free-flowing and contained within the case. It allows rapid scanning or indexing.

Fig. 1 shows the cartridge. A rectangular plastic box 1 has an opening 1a at the top, showing a free rolling spindle 2 around which belt 3 is hanging. The belt hangs free and is folded within the cartridge. Another opening 4 is on the front of the cartridge.

Fig. 2 shows the cartridge half inserted. When fully inserted in the machine, Fig. 3, the open end of the cartridge first, spindle 2 with the belt comes in contact with a driving spindle 5 driven from motor 6 by three activators: one for low- forward speed, one for low-reverse speed, and one for high-forward speed.

The record/reproduction head 8 comes in contact with the belt through opening 4 in the cassette.
