Abstract:
1. A library apparatus for receiving a read/write request from a host to read/write data from/to a storage device, the apparatus comprising: a medium name storage unit that stores medium name conversion information in which a virtual medium name specifying a storage medium in the read/write request, is related to a real medium name specifying the storage medium in the library apparatus; a conveying mechanism unit that conveys the storage medium; a drive that reads/writes data from/to the storage medium conveyed by the conveying mechanism unit in response to the received read/write request; a conversion unit that converts the virtual medium name included in the received read/write request to the real medium name on the basis of the medium name conversion information stored in the medium name storage unit; and a conveying mechanism control unit that controls the conveying mechanism unit to convey the storage medium having the real medium name converted by the conversion unit to the drive, wherein the apparatus includes storage mediums of different generations, drives of different generations accepting the storage mediums of different generations and a generation compatibility information storage section configured to store generation compatibility information indicating which generation of the storage mediums is available for each of the drives of different generations, the conveying mechanism control unit controls the conveying mechanism unit so that the conveying mechanism unit conveys the storage medium to the latest generation drive of the drives available for reading/writing data from/to the storage medium according to the generation compatibility information, and the latest generation drive reads/writes data from/to the storage medium conveyed by the conveying mechanism unit in response to the read/write request.
