<p>PURPOSE:To improve the resposibility of rotational speed of a jogging dial and the running speed of a tape in a low-speed rotating are of the dial and to suppress the unevenness of a tape running caused by the unevenness of the dial rotation in a high-speed rotating area of the dial. CONSTITUTION:In the low-speed rotting area of the jogging dial 1, a tape running system 6 is controlled based on a dial FG pulse itself as pulse data. Then, in the high-speed rotating area of the jogging dial 1, the tape running system 6 is controlled based on an integrally processed dial FG pulse as pulse data.</p> |
