Abstract
PURPOSE: To realize the constitution of the control loop which is several times as accurate as the single head, by regenerating the control signal recorded on the magnetic tape by the several units of control signal magnetic heads.
CONSTITUTION: Video heads 1 and 2 plus rotary phase detecting magnet 3 each are attached to rotary disk 4, and rotary phase detector 5 is provided to the fixed part in correspondence to magnet 3. Disk 4 is driven by DC motor 6, and the output signals of detector 5 and reference oscillator 10 are supplied to rotary head servo circuit 8. And the output signal of circuit 8 is supplied to motor 6 via driving circuit 9 to secure the phase control for disk 4 at the reproducing time. On the other hand, the output signals of both oscillator 10 and control head group 19 are supplied to capstan servo circuit 18, and the output signal of circuit 18 is supplied to motor 15 via driving circuit 22. Thus both the velocity and the phase are controlled for capstan 11.
