<p>PROBLEM TO BE SOLVED: To provide a magnetic recording/reproducing device capable of obtaining the satisfied head touch with the different number of drum rotation. SOLUTION: A movable post 17 is provided between the inlet side of the rotary drum 6 and a tension post 11, and the movable post 17 is moved to the position not in contact with a magnetic tape 1 when the number of rotation of the rotary drum 6 is R1. When the number of rotation of the rotary drum 6 is R2 (R1), by the movement of the movable post 17 up to the position wound with the magnetic tape 1, the tension at the inlet side of the rotary drum 6 is increased without changing the tension of the tension post 11.</p> |
