Abstract
A library apparatus where multiple moving commands generated by several upper-order units are conveyed to a director. The moving commands may be sequentially conveyed through the same channel or may be simultaneously conveyed through different channels. The moving commands are then conveyed to an accessor controller which includes a queuing table for storing the commands. The queuing table permits the accessor controller to receive additional commands prior to the execution of the previous command. Therefore, the processing speed of the system is increased. Next, the commands are conveyed to a plurality of accessors which transfer the medium cartridges to the desired location. Several accessors may be operated simultaneously in parallel. The simultaneous operation of several accessors also increases the efficiency and speed of the system.
