Abstract
In a magnetic tape transport device having supply and take-up reels and tape guide elements, as well as a scanner, there is engaged with the tape on each side of the scanner a tape tension roller on the free extremity of a tape tension lever which is subjected to torque at its pivot by a d.c. motor for maintaining the desired tension of the tape. An angular position indicator is connected to the pivot of the lever and a regulation loop is provided for controlling the tape tension in a manner consistent with the tape speed. A capstan drive of the tape is not necessary.
