ABSTRACT:
A method and apparatus for controlling the capstan servo of a magnetic video tape recording and reproducing machine is disclosed. The invention provides almost instantaneous color framing and synchronous control track lock when accelerating from a very slow tape velocity up to normal velocity. An embodiment of the apparatus also stops the tape at a predetermined position relative to control track transitions when stopping the machine from a noncontrol track lock operating mode, such as shuttle, variable velocity reproducing and jog.
