Abstract
In a media library apparatus, common addresses are imparted to storage shelves of a plurality of storage columns in corresponding relation to respective predetermined physical locations of the storage shelves in such a manner that each group of the storage shelves of the storage columns lying at a same physical location within the library apparatus is uniquely identifiable by a specific one of the common addresses. In a data striping process, a data read/write operation is performed on the media transported from a group of the storage shelves to which is imparted a specific one of the common addresses. Thus, a plurality of the media to be subjected to the data striping process can be managed collectively through designation of only one address. Namely, the media designation can be greatly simplified by just performing control such that the media stored in the same-address storage shelves of the individual storage columns are transported to the respective drive devices. There are also provided extra storage sections for storing abnormal and spare media. When an abnormal condition occurs in any one of the media during the data write operation, the abnormal medium is automatically rep…
