Abstract
In an apparatus for recording video signals within recording tracks extending obliquely across a magnetic tape, having a rotary drum with first and second pairs of heads spaced from each other pair by a distance corresponding to one track pitch in a direction parallel to the axis of the rotary drum for recording video signals simultaneously on two recording tracks, while sequentially recording video signals on the magnetic tape within the recording tracks the video signals are recorded on said magnetic tape for longer than at the time of normal recording in such a manner that one of the two recording tracks on which the video signals are recorded by one of the second pair of heads overlaps part of the other recording track which is next to the one recording track and on which the video signals are recorded by one of said first pair of heads, so that by controlling the moving speed of the moving means in such a way so as to be slower than the normal moving speed at the time of normal recording, reductions in the signal to noise ratio can be avoided, and effective long time period recording can be achieved.
