Zusammenfassung:A disk and navigation apparatus for reproducing the disk in a position locating system wherein the maps are more clearly displayed without requiring a large increase in the amount of data storage capacity required. On the disk there are recorded in a frequency division multiplex mode a video FM signal of a first frequency band obtained by frequency-modulating a video signal containing map data, and a video digital signal of a second frequency band obtained by digitizing and digitally modulating a video signal indicative of a travel path of the map data along which the object to be guided moves. The video digital signal of the travel path in a picture is located on the same track as the video FM signals of N (integer) fields of the corresponding picture.
