Abstract: Magazine insertion is detected and suction of the magazine toward the deep end of a data library device casing is started. An identification code recorded on a recording medium cassette contained in the magazine is read at the timing when the cassette passes a read area of a read device arranged on the data library device case and stored in correspondence with the storage position. Operation is performed according to the storage when transferring the recording medium cassette between the magazine and a drive.
