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 real table and a plurality of virtual tables. The contents of one of the virtual tables is switched to the real table. Accessors are operative in accordance with the contents of the real table. The switching of contents from virtual tables to the real table enables the accessor controller to act as if two operation commands exist instead of one command so that a plurality of accessors can operate simultaneously.
