Abstract
The present invention is directed to a data cartridge library system that realizes a reduced cost by reducing the number of certain components, especially expensive components, that are needed to perform certain functions within the library. With respect to certain functions, a reduced cost is realized by using lower precision compenentry in combination with componentry that compensates for lower precision while still providing a reduced component cost with respect to a given function. In one embodiment of the invention, a data cartridge picker is provided that: (1) uses a single electro-mechanical device for the functions of grasping a data cartridge, retracting a grasped cartridge from a drive/storage location, inserting a grasped cartridge into a drive/storage location, and releasing a grasped cartridge once position in a desired location; (2) is capable of compensating for variations in cartridge positioning; (3) has a gripping mechanism that. moves in a sinusiodal manner; and (4) avoids the wear and tear associated with moving fully retracted gripper mechanism that is not holding a data cartridge from a fully retracted position to a position at which a cartridge can be retrieved. Another embodiment provides a elevator mechanism for moving the cartridge picker in which the guiding portion of the mechanism is also part of the portion of the mechanism that moves the cartridge picker.
