徴とするコントロール信号補正装置。[Claim for Utility Model Registration] The control signal reproduced from the control track of the magnetic tape by the control head is amplified by the reproduction amplifier, and after being waveform-shaped by the next waveform shaping circuit, it is used as the servo reference signal. In a video tape recorder configured to send data to the next-stage servo system, a voltage holding circuit converts the control signal from the playback amplifier into a DC voltage and holds the peak voltage; a VCO that oscillates at a frequency proportional to the peak hold voltage held;
It is equipped with a Schmitt trigger that shapes the output, and an OR circuit whose inputs are led to the output of the Schmitt trigger and the output of the waveform shaping circuit, and the output of the OR circuit is used as a servo reference signal to control the servo of the next stage. A control signal correction device characterized in that the control signal correction device is configured to send the control signal to a system.
