Abstract:
A method for controlling a phase of a capstan motor during slow playback mode in a VCR, the capstan phase control method comprising the steps of:(a) generating a reference control signal having a frequency and phase corresponding to a desired slow playback speed on the basis of a head switching signals;(b) reading a control signal from a tape corresponding to said slow playback mode;(c) judging whether the phase of the reference control signal generated in the step (a) is the same as that of the control signal read in the step (b);(d) calculating a phase error to make the phase of the read control signal coincide with that of the reference control signal on the basis of the judgement result of the step (c); and(e) controlling the phase of the capstan motor using the phrase error calculated in the step (d).
