In one aspect of the invention, an apparatus for handling storage cartridges within an automated storage library is provided. In one example, the apparatus includes a frame, a translating member, e.g., a leadnut/leadscrew, and a finger mechanism slidably mounted to the frame. The translating member is operable to translate along the frame. The finger mechanism includes a finger member for engaging a storage device, and the finger mechanism is mechanically associated with the translating member such that translation of the translation member relative to the picker frame results in a translation of the finger mechanism relative to the translation member such that the finger mechanism moves a greater distance than the translation member. A gear assembly, mounted to the translation member, may rotate during translation to cause relative movement of the translation member and finger mechanism.
