Abstract

PURPOSE:To obtain the titled system which effectively exhibits functions, such as program searching, by making the tape speed at the time of fast forwarding rewinding by using a control signal of a VTR tape uniform, and by stabilizing reproductions of signals from a sound track and those of clocks and address signals from the output. CONSTITUTION:The control signal of a head 30 for a control track is introduced to an AFC circuit 31 and an APC circuit 32. The AFC circuit generates a control signal in which the frequency of the reproduced signal is made constant. The APC circuit 32 generates a control signal which uses the phase difference between a reference pulse signal and the reproduced control signal pulse as a set value. Both the control signals are given to a winding motor controlling circuit 35 through an adder 34 and control the number of revolutions of a motor mechanism 36. Since the tape speed at the time of fast forwarding and rewinding is controlled by utilizing the control signals in such a manner, reproductions of the clock and address signal can be performed stably and surely.
