Abstract
A library apparatus capable of directly entering a large number of recording medium cartridges all at once into a given cell column of a cell drum. The library apparatus includes a recording medium drive unit for writing and reading data to and from a recording medium cartridge; a cartridge entry unit for entering recording medium cartridges into the library apparatus; an automatic cartridge exit unit for automatically ejecting recording medium cartridges from inside the library apparatus; and an accessor for transporting recording medium cartridges through the cell drum, recording medium drive unit, cartridge entry unit and automatic cartridge exit unit. The library apparatus further includes a swinging door that opens and closes to allow recording medium cartridges to enter all at once into the cells of a given cell column in the cell unit, and a faulty cartridge entry detection mechanism for detecting any faulty entry of a recording medium cartridge into any cell of the cell column. The data about that cell column in the cell drum in which cartridges were switched are stored into a nonvolatile memory in an accessor controller that controls the accessor.
