Title: Rotary magnetic head device and magnetic recording and reproducing device using the same
Inventor: OKADA SHINJI
IPC: G11B15/60
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to assure an optimum tape tension even with magnet tapes varying in coefficient of friction and to obtain good reproduction by detecting the tension of the magnet tape in the traveling section of the magnet tape and feedback-controlling the detected value to make the tape tension constant. SOLUTION: When the tape tension Tc on the rotary drum outlet side increases, a tension ball 19a is pulled in X direction and felt 21 adhered to a tension pad 20 acts in a direction where the felt parts from a brake drum 24, thereby decreasing the brake force applied thus far on the brake drum 24. The tension of the delivered tape decreases, making the tape tension Tc constant. When the tape tension Tc decreases, the brake force acted thus far on the brake drum 24 conversely increases and consequently the tension of the delivered tape increases, making the tape tension Tc constant. Even if the coefficients of friction of the various tapes vary, the tape tension Tc is kept constant.
