Magnetic reproducing apparatus having a capstan servo circuit

A magnetic reproducing apparatus having a capstan servo circuit, said reproducing apparatus comprising rotary heads for reproducing a recorded video signal from tracks which are formed obliquely to the longitudinal direction of a magnetic tape, a drum motor for rotating said rotary heads, and a capstan motor for rotating a capstan which drives said magnetic tape to travel, said capstan servo circuit comprising:

• detecting means for detecting a rotation of said drum motor, and for producing a detection signal which is in accordance with the rotation of said drum motor;
• reference signal generating means for generating a reference signal;
• synchronizing means for synchronizing the phase of the reference signal which is generated from said reference signal generating means and the phase of the detection signal which is produced from said detecting means during a high-speed reproducing mode of said reproducing apparatus;
• a control head for reproducing a recorded control signal from said magnetic tape;
• phase comparing means for comparing the phase of the control signal which is reproduced by said control head with the phase of the reference signal which is generated from said reference signal generating means, and for producing an output signal;
• and
• control means for controlling a rotation of said capstan motor by the output signal of said phase comparing means.
