Abstract

PURPOSE:To exactly scan a head and a track at the time of special reproduction and always obtain a reproduced picture having no noise, by utilizing the information having a control signal, and always knowing of the position related to a rotary head and a video track. CONSTITUTION:The video heads 1, 2 are mounted to the electrical-mechanical conversion elements 21, 22, the rotary phase detection magnet 3 is mounted to the rotary disk 4, the disk 4 is rotated by the DC motor 6, and the motor 6 is rotated by the output of the disk servo-circuit 8 which inputs the outputs of the frequency generator 7 and the rotary phase detector 5. Also, the magnetic tape 23 is driven through the capstan 11 and the pinch roller by the DC motor 15. And, the output of the frequency generator 16 and the output of the reproduction speed indication part 35 are provided to the capstan control circuit 36, and the motor 15 is driven through the driving circuit 32. Furthermore, the output of the control head 17 and the output of the rotary phase detector 20 are input to the arithmetic circuit 33, the rotary angle of the capstan 11 is detected by the disk with slit 19 and the detector 20, and scanning is executed exactly.
