PROBLEM TO BE SOLVED: To shorten a time required for a moving operation of a tape medium in writing data to a tape medium. SOLUTION: In a controller 16 of a tape drive, when a command processor 41 receives a command for moving to the end of data (EOD) or the like, an operation signal output unit 45 suspends the moving of a tape and a cartridge memory (CM) input/output unit 44 stores therein a state of the tape in which the moving has been omitted. Then, when the command processor 41 receives a command for writing data in this state, the CM input/output unit 44 writes the data to a cartridge memory. Subsequently, for example, when a head passes a proper position at which the data should be actually written to the tape, the CM input/output unit 44 reads the data from the cartridge memory, and a channel input/output unit 43 writes the data to the tape at the proper position.
