Abstract
A retention spring for a tape cartridge that both secures a leader pin and operates as a wide angle guide for directing the leader pin into the access port of the cartridge as the tape is being rewound onto the supply reel. The retention spring includes pairs of opposing guides, retention grooves, and binding elements. The guides define an entry for receiving a portion of the leader pin while the retention grooves define a retention slot for at least partially surrounding a portion of the leader pin. The binding elements each define a transition between one guide and one retention groove while providing resistance as the leader pin is urged between the entry and the retention slot.
