    • PROBLEM TO BE SOLVED: To obtain a reel capable of preventing the deformation and damage of a recording tape near an outer peripheral surface of a hub by reducing the deformation of the hub due to tightening by winding during winding of the recording tape, a recording tape cartridge, a machine reel, and a drive device. SOLUTION: The outer peripheral surface of the reel hub 22 is subjected to electroless nickel plating M of a thickness 0.008 to 0.025 mm to thereby enhance the rigidity of the reel hub 22, and to prevent the deformation and damage of the recording tape T near the outer peripheral surface of the reel hub 22. Then, an upper flange 24 and a lower flange 26 are also deformed accompanying the deformation of the reel hub 22 and the deformation of the upper flange 24 and the lower flange 26 is suppressed by high rigidity of the reel hub 22 and the damage of the tape edge of the recording tape T generated by narrowing of the internal space constituted of the upper flange 24 and the lower flange 26 can be prevented, and the tape traveling position of the recording tape T can be stabilized.

    • PROBLEM TO BE SOLVED: To precisely position a cleaning brush with respect to a magnetic head, with a simple structure, in a recording/reproducing device using a leader tape. SOLUTION: A brush driving mechanism for driving the cleaning brush (18) from a retracting position to the operational position facing the magnetic head (16a) is provided with a main arm (35) to whose tip the cleaning brush is connected via a shaft (36). A chassis (12), into which the shaft is inserted, is formed with a chassis groove (121) for moving the cleaning brush from the retracting position to the operational position, by operating the main arm. The tip part (121a) of the chassis groove locks the shaft when the cleaning brush is at the operational position, and positions the cleaning brush with respect to the magnetic head.
