A first system adaptation unit of magnetic tape drive apparatus communicates with a read/write request source based on a method adapted to a file system. A second system adaptation unit communicates data with the read/write request source based on a method adapted to a designated system other than the file system. A control unit allows the first system adaptation unit to be in a ready state when a format of a magnetic tape to be read and written is adapted to the file system and allows otherwise the first system adaptation unit to be in a not-ready state. The control unit deceives the read/write request source as if the first system adaptation unit is in the ready state even when the first system adaptation unit is in the not-ready state as well as the ready state.

A control unit refers to a logical library information storage unit in response to a reception of an export process command from an external device, identifies one of the logical library units which is correlated with a physical recording medium in a physical library unit which has been ordered by the export process command to been ejected from an ejection slot, and correlates, in the identified logical library unit, the ejection slot to a logical recording medium which is correlated to the physical recording medium which has been ordered to been ejected.
