ABSTRACT:
In an apparatus for automatically maintaining a transducing head assembly on the proper track, which is particularly adapted for a helical scan recording and/or reproducing apparatus capable of providing special motion effects, track selection method and apparatus is disclosed. The apparatus is of the type which utilizes transverse positioning of the transducing head to accurately follow a track during reproducing and, at the completion of the reproduction from the track, to properly position the head in position to either reproduce the next adjacent successive track, reproduce the same track or reproduce another track so that the appropriate special motion effect is achieved. During the acceleration of the tape to normal speed, the tape transport is initially controlled relative to a recorded control track to position the head relative to the recorded tracks so that the reproduced video signal is color framed with respect to studio reference. Verification of color framing is performed after reaching normal speed by detecting the H sync to V sync phase relationship of the reproduced video signal and deflecting the movable head 1 track position along the tape to obtain proper color frame conditions if initial color framing was incorrect.
