ABSTRACT:
A single reel tape cartridge is disclosed for an automatic threading tape drive. The reel includes layers of magnetic tape with a leader block attached to the free end of the tape. The leader block is held in a receiving well in one corner of the cartridge when the cartridge is out of a tape drive. The leader block interconnects with a threading pin in the drive for threading the tape through the drive to a take-up reel hub. The leader block includes conforming sections that fit the leader block into a U-shaped channel in the hub to provide a smooth hub periphery for the layers of tape.
