Abstract
The unit works in conjunction with a multiple-disc player by storing the empty disc-cases, indicating disc status, and providing a system of selection for the discs inside of the multi-player. The unit stores empty disc-cases in relative positions to discs stored inside the multi-player. The exposed faces of stored disc-cases behave as buttons and labels.
