    摘要: The disclosed recorder includes a motor, a magnetic head, an oscillation circuit connected to the head, an equalizing circuit connected to the oscillation circuit. The equalizing circuit includes a capacitor which, when grounded, changes the equalization of the equalizing circuit. A signal amplifier is connected to the equalizing circuit. A speed changing circuit is connected to the motor for changing the speed of the motor and, hence, the tape speed, and a switch forms an operating path when closed for simultaneously connecting the speed changing circuit to ground through the path so as to energize the speed changing circuit and connects the capacitor to ground through the same path so as simultaneously to change equalization of the equalizing circuit.
