Abstract
A method for recording a frame control signal serving as a reference signal of a video frame during recording, and for generating a frame control signal in a VTR (video tape recorder) from a control track based on a control signal during reproduction, wherein the video signal is recorded on and reproduced from multiple video tracks using multiple heads. The method for generating the frame control signal comprises the steps of using a microprocessor to determine whether a VTR is in the record or playback mode, counting the number of rising edges of the control signal, recording the control signal at 60% duty cycle or .alpha. % duty cycle based on a derived value 'n', generating a frame control signal and controlling the phase of a capstan motor. As a result, the frame control signal serving as a reference signal of the video signal is commonly held on the control track of the video tape with other control signals, so that the controlling of the phase of the motor and of the video signal is enhanced by microprocessor programming.
