ABSTRACT:
An apparatus for recording and reproducing a video signal records all of effective line information required for transmission of respective picture images and voice information together with identification information in mutually resembling track patterns by setting the number of sampled picture elements per line (or block) and the number of lines (or the number of blocks) to be recorded in each track in accordance with a band ratio m of a first record video signal to a second record video signal. With this, it is possible to record and reproduce a plural types of video signals having mutually different bands and also different number of effective scanning lines and signal formats by one apparatus efficiently while checking enlargement of a circuit scale and with almost uniform picture quality performance in accordance with the difference of the bands.
