Method and system for selecting and moving a single disc in an optical disc library

A method comprising:

• moving a disc gripper device until the disc gripper device is positioned above a disc cassette positioned on a side of a guide cage;
• and
• lifting a disc from the disc cassette upwards into the disc gripper device via a disc selector system comprising:
• a motor;
• and
• a disc selector mechanism coupled to a bottom of the guide cage and maintained in a space below the guide cage;
• wherein the disc selector mechanism comprises a shaft, a slide laterally slidable along the shaft in response to the motor driving the slide, a pivot bar coupled to the slide, and a pick blade pivotally coupled to the pivot bar;
• and
• wherein a linear motion of the slide along the shaft drives a linear translation of the pivot bar, and the linear translation drives the pick blade to move to out of the space and pivot to a raised position to contact and lift the disc upwards into a disc gripper device.

A computer program product comprising a computer readable storage medium having program code embodied therewith, the program code being executable by a computer to implement a method for selecting and moving a single disc in an optical disc library, the method comprising:

• moving a disc gripper device until the disc gripper device is positioned above a disc cassette positioned on a side of a guide cage;
• and
• lifting a disc from the disc cassette upwards into the disc gripper device via a disc selector system comprising:
• a motor;
• and
• a disc selector mechanism coupled to a bottom of the guide cage and maintained in a space below the guide cage;
• wherein the disc selector mechanism comprises a shaft, a slide laterally slidable along the shaft in response to the motor driving the slide, a pivot bar coupled to the slide, and a pick blade pivotally coupled to the pivot bar;
• and
• wherein a linear motion of the slide along the shaft drives a linear translation of the pivot bar, and the linear translation drives the pick blade to move to out of the space and pivot to a raised position to contact and lift the disc upwards into a disc gripper device.
