Abstract
A cartridge containing a single supply reel of magnetic tape is inserted into an adapter which converts the cartridge format to the VHS standard format. The adapter includes an interlock system which prevents the acceptance of the adapter by the VHS machine until the magnetic tape on the supply reel is advanced onto the take-up reel of the adapter.
