The present invention provides a magnetic tape apparatus comprising: a tape drive for recording and reproducing data to/from a magnetic tape; a firmware memory containing firmware; and a controller for controlling the tape drive by executing the firmware, wherein the controller causes the magnetic tape apparatus to: read out a VOLID mark from an attribute information recorded between the BOT and a data on the magnetic tape; detect a volume identifier contained in the VOLID mark; decide that the data is firmware if the volume identifier contains a predetermined control code; and if the data is decided to be firmware, to overwrite the firmware recorded on the magnetic tape medium, upon the firmware memory.
