Abstract: PURPOSE:To attain correct verify operation by controlling the recording and reproducing circuits of two pairs of revolving magnetic heads on a revolving drum to an active or inactive condition according to timing decreasing the amplifying degree of reproducing in correspondence to a recording width. CONSTITUTION:With a first timing, in which revolving magnetic heads 203A and B are traced on a magnetic tape, the recording circuit is controlled to the active condition and with a second timing, in which magnetic heads 203C and D are traced, the above-mentioned circuit is controlled to the inactive condition.
