An apparatus for recording video data by forming many tracks on a recording medium and/or for reproducing the video data from the tracks is provided with a memory which is arranged to have recording video data or reproduced video data supplied thereto. The apparatus detects the picture change-over portion of the video data obtained within the tracks and controls, in accordance with the detected position, an offset degree between the writing and reading addresses of the memory.
