ABSTRACT:
A magnetic tape drive for driving a magnetic tape stored in a cartridge for writing and reading data as an external storage device of a computer, etc., and equipped with a leader block at a distal end thereof, comprises a file reel having the cartridge fitted thereto, and a machine reel rotating in the same direction as the file reel while the leader block is fitted to a hub thereof, and taking up the magnetic tape, wherein data is written/read to and from the magnetic tape in a travelling path between the file reel and the machine reel. In this construction, the magnetic tape is wound at an initial tension lower than a normal tape tension at the start of winding of the magnetic tape by the machine reel until a predetermined number of turns of the magnetic tape is wound on the machine reel, and thereafter the tape is wound at a greater tension. As a result, the leader block can be correctly fixed to the hub of the machine reel, and even when a thin magnetic tape is used, read/write errors do not occur, and the apparatus can be made more compact.
