Abstract

PURPOSE: To attain excellent reproduction even with special reproduction VTR, by controlling the feed of an original tape according to the speed ratio of recording to reproduction.
CONSTITUTION: Magnetic head 7 comes into contact with original tape 1 at a fixed part and a signal from head 7 is supplied to time code reading circuit 8, which reads the time code of tape 1. Similarly, the time code of master tape 4 is also read out and further a time code from reference time code generator 12 is supplied to processing circuit 9 together. With the signal from circuit 9, motors 3 and 6 are controlled. Then, set signals such as speed ratio (x) of tape 1, time code Tcx of a video start end and fixed-part start code Tcr of tape 5 are supplied from terminal 14 to circuit 9. On the basis of data in memory 5 storing a process program, circuit 9 feeds tape 1 and with the time code of generator 12, reproduction is started. Then, the time up to the desired video start end of tape 1 is calculated and the phase of tape 1 is adjusted so that the obtained time will be (x) times the time up to the reproduction time. At time Tcr, the time code of tape 1 becomes Tcx and reproduction is done.
