A magnetic tape automatic recording apparatus wherein a variable resistor is provided in the recording circuit for regulating the recording level, an operating shaft is rotated by a first driving device in the direction increasing the recording level in response to the initiation of the recording, rotation of the operating shaft is prevented in response to the output of a detecting circuit detecting that the recording level has reached a predetermined value, and is effected by a second driving device in the direction decreasing the recording level in response to the termination of the recording.
