Abstract
Abstract An apparatus for recording a video signal while forming a multiplicity of recording tracks in parallel on a tape-shaped recording medium, wherein camera information representing the operating state of a camera when shooting each picture is recorded in a position corresponding to the recorded track of that picture so that the operating state of the camera at the time of taking the video signal which has already been recorded can reappear. Therefore, in a case where a video signal is recorded in continuity with this recorded portion, the camera operating state is controlled in a joint portion of these to improve the continuity in this joint portion.
