Abstract

PURPOSE: To prevent disturbance of the reproduced screen, by providing a rotation speed detedtor of a capstan motor, a control signal detecting circuit, a switch circuit, and an adder where the control signal is inputted in the magnetic recording and reproducing device.
CONSTITUTION: In the magnetic recording and reproducing device, selector switches 13 and 14 are connected to the reproducing-side contact P side at a reproducing time, and the control signal reproduced from the magnetic tape by control head 5 is amplified into pulses by amplifier 12 and is inputted to the adder and signal detecting circuit 16. In this case, the output signal of control signal detecting circuit 16 is applied to switch circuit 17 for switching control, and switch circuit 17 inputs the control signal to output adder 15 when the control signal is high-level. As a result, even if control pulses are dropped out, the tape runs at the speed synchronized with the reference signal, so that disturbance of the screen can be prevented.
