Abstract
PURPOSE: To prevent the cumulation of an error in case when the locating operation has been executed repeatedly, by correcting the value of a moving amount designating signal provided to the next time, by means of the error between the point where the recording medium has actually stopped and the objective point, in the stationary servo-device which is used for VTR, etc.
CONSTITUTION: After a reset signal has been provided to the counter and it has been reset, the moving amount of a tape is designated. As a result, a moving amount designating signal is output by the moving amount designating signal generating circuit 12, and this signal is provided to the preset data terminal of the counter 11 through the adder 13. And the moving amount of a tape can be derived, for instance, in accordance with an address signal, etc. recorded at every track of the tape. That is to say, the value of a moving amount designating signal provided to the next time can be corrected by means of the error between the point where the recording medium has actually stopped and the objective point. In this way, in case when the locating operation has been executed many times repeatedly, the cumulation of an error can be prevented.
