ABSTRACT:
A video and audio signal recording apparatus for recording video and audio signals on parallel tracks formed on a recording medium, includes: a divider for dividing a video signal into video signal blocks each contained in a unit period which is N times (N=1, 2, . . .) as long as one field period of the video signal; another divider for dividing an audio signal into audio signal blocks each contained in a specific period which is synchronized with the unit period; and a recorder for recording signal contained in each of said video signal and audio signal blocks in each of fully independent areas on the recording medium such that any two of the fully independent areas adjacent to each other in a track width direction are separated from each other by an unrecorded area composed of L unrecorded consecutive tracks (L=1, 2, . . .) and any two of the fully independent areas adjacent to each other in a track length direction are separated from each other by an unrecorded area having a specific length in the track length direction.
