ABSTRACT:
The present invention is for realizing the improvement of the cartridge storage efficiency and size reduction of a library apparatus by installing relative flags using cells of a storage rack to suppress the increase in the installation area or volume of a locker resulting from the installation of the relative flags, and further for shortening the time required for the initial operation of an accessor. For these purposes, a positional correction relative-flag structure of the cartridge storage rack is equipped with a body section which is inserted into the cell of the storage rack to be brought closely and fixedly into contact with the cell, and a relative flag to be read out by an sensor on the accessor side for the correction of the position of the storage rack is attached to an end surface of the body section. This invention is applicable to a large-capacity external storage memory storing a large number of cartridges such as magnetic tape cartridges and optical disk cartridges.
