Description

ABSTRACT OF THE DISCLOSURE A high-speed reproducing system is used in a magnetic reproducing apparatus having a reel for taking up a magnetic tape on which an information signal and a control signal have been recorded and means for reproducing the information signal from the magnetic tape. The system comprises a control head for reproducing the control signal from the magnetic tape, a frequency-voltage converter for producing as output a voltage in responsive correspondence with the frequency or period of the control signal thus reproduced, a reel motor for driving the reel in rotation, and a circuit for controlling the reel motor to rotate in response to the voltage thus produced as output. The reel motor is controlled of its rotation so that the magnetic tape is travelled at a constant high speed.
