Abstract
A video signal recording method and apparatus for-recording each field of a video signal as a plurality of segments on respective tracks of a magnetic tape, in which each segment consists of a sequentially-ordered set of scanning lines which constitute a fraction of the total scanning lines of the field and which extend substantially over the entire field, for example all of the even-numbered or all of the odd-numbered lines of the field. Since each recording track contains scanning lines extending sequentially over one field, a playback signal providing a correctly ordered display image is obtained for playback operation at speeds higher or lower than the standard speed, while utilizing the same recording and playback signal processing circuits as are utilized during standard speed operation.
