<p>PURPOSE:To obtain the state of position between a track and a rotary track at tape stopping in the same state for each function by making a time till the tape stops after a control signal is detected the same for a slow reproduction control circuit and a play-still reproduction control circuit. CONSTITUTION:The tape moving quantity from the detection of the control signal till the stop of a tape is designed to be the same as the slow reproduction control circuit and the play-still reproduction control circuit. Even in case of slow reproduction and play-still reproduction, the tape speed is the same before and after a point of time of detecting a control pulse and the tracking state when the tape is stopped completely after a brake voltage is applied is the same for both the slow reproduction and the play-still reproduction. Thus, the play-still reproduction is obtained quickly without the need of framing as a conventional device. Moreover, no longitudinal and lateral fluctuation of the pattern caused by framing takes place and a stable still pattern is obtained.</p> |
