<p>PROBLEM TO BE SOLVED: To provide a servo device for the high speed reproduction of digital VCR. SOLUTION: The servo device for digital video tape player, which records video data that is highly efficiently encoded by a division recording system on a position where a head travels and which reproduces data by a spiral scanning system at high speed, is provided with a head drum motor 90 having prescribed speed by high speed reproduction and outputting a head rotation signal, a rotation drum servo part, a capstan motor 100 and a vertical position detection part 10 using the output signal of the head drum motor 90 and a system clock. Furthermore, the servo device is provided with a horizontal position detection part 20 for a video tape, which uses a signal that is read from the video tape, the bead track adjusting part 30 for generating a speed varying signal where the head travels on a position on which intraencoded video data is recorded by using vertical/horizontal position data and previously stored head track information for high speed reproduction and a capstan servo part receiving the speed varying signal and the output signal of the capstan motor 100 and controlling rotation speed.</p> |
