The purposes of the study are to formulate a mathematical model of mechanical tension arm system including supply reel and capstan system, and to simulate dynamic reponse according to parameter variations of the componests in tension arm system. Experiments were carried out in order to prove the validity of the mathematical model. From the results of simulations and experiments, dynamic responses of tape tension and displacement of tension post were analyzed during entire playing mode and they showed the basic characteristics of the tension arm system.

In the present study, the following factors are analyzed systematically using the theoretical and experimental methods, which have the significant influence on the quality of VTR tape path system in order to develope the high performance and quality in VTR mechanism: 1) Vibration characteristics of the deck including the tape path sytem, 2) Modeling the global tape path, 3) Torsional vibration of the VTR drum. 4) Capstan system, 5) Tension bar, 6) Stick-slip phenomenon of the running tape.
