ABSTRACT:
A device for controlling tension in an elongated article arranged along a path, and a tape recording and/or reproducing apparatus including such a device, in which a control circuit influences the tension in the article, such as a tape, responsive to an electrical signal which is related to a moveable tension sensor. The electrical signal is varied by moving a metal part arranged as a damping element for a single coil only, so as to vary the quality factor (Q) of the coil.
