ABSTRACT:
A recording and reproducing apparatus in which signals are recorded onto and reproduced from a magnetic tape wound around a peripheral surface of a rotary drum by magnetic heads which are attached to the peripheral surface of the rotary drum corresponding to a plurality of channels, respectively, comprises at least: a detector to detect an envelope level of a reproduced RF signal which is derived from the magnetic head every channel; a comparator to compare the detection output and a reference level and to generate a control voltage corresponding to the magnetic head every channel; a latch to store the control voltage; and a circuit to make the envelope level of the reproduction RF signal constant in accordance with a predetermined timing for supplying the control voltage.
