  • Patent number: 4476500
    Abstract: A tracking apparatus for a video tape recorder having an auto-tracking servo system which enables plural video heads to be automatically on-track by means of the mechanical displacement of plural electro-mechanical conversion elements having the plural video heads respectively mounted thereon. When track-jumping occurs, the apparatus determines which of the plural heads is creating the track jumping and further determines the compensating direction needed to change the scanning track. The apparatus then controls the position of the head creating the track jumping so as to eliminate the track-jumping.
