When recording video data in a plurality of recording blocks on a recording medium while organizing the video data into navigation units, the present invention records the size of the first picture data in each of the navigation units expressed in terms of the number of transport packets carrying the first picture data. Alternatively, the present invention adds 128-byte header information to each of the recording blocks, in which case if a recording block contains the last data of the first picture in each of the navigation units, position information for indicating the end position is written in the header information. The present invention thereby can specify-the data section of the first picture in each navigation unit precisely.
