Abstract
Abstract A magnetic disk cartridge loading-and-unloading device for loading a magnetic recording disk cartridge into a recording and reproducing system and unloading it from the recording and reproducing system comprises a movable member, first and second holding members which are adapted to grasp the magnetic recording disk and are mounted on the movable member near to each other to be moved together with the movable member and a controller which controls the movable member and the first and second holding members. Under the control of the controller, the movable member brings the first holding member to a position in which the first holding member grasps a first magnetic disk cartridge supplied by a supply conveyor, then brings the second holding member to a position in which the second holding member grasps a second magnetic disk cartridge ejected from the recording and reproducing system with the first holding member holding the first magnetic disk cartridge, then brings the first holding member to a position in which the first holding member loads the first magnetic disk cartridge in the recording and reproducing system with the second holding member holding the second magnetic disk cartridge, and brings the second holding member to a position in which the second holding member delivers the second magnetic disk cartridge to a discharge conveyor.
