Abstract: The present invention includes a navigation process and a navigation system for a vehicle, especially a motor vehicle, a ship or aircraft, for navigating the vehicle from a starting position to a destination, in which a predetermined destination and, if necessary, a starting position are input into the navigation system. In this navigating method one or more predetermined numbers designating the predetermined destination and, if necessary, the starting position are input to the navigation system; then the one or more numbers are correlated with one or more position addresses from a position address list provided in a memory device and are read out from the memory device; and the one or more position addresses output from the memory device are assigned as the destination and, if necessary, the starting position. Preferably the numbers input to the memory device are telephone numbers of telephones located at the different destinations and the memory device includes a CD-ROM.

Abstract: The tape of a video cassette providing oblique recording tracks of a longitudinal sound track for relatively narrow-band sound and a control track for vertical scan frequency synchronizing signals, instead of being usable alternately either for recording stereo and other wide-band sound on the oblique tracks and for recording television signals with sound either on the oblique tracks or on the longitudinal sound track, can be used for noninterfering superposed recording of sound on the oblique tracks using the usual FM sound signal carriers and a full television signal with the related sound on the longitudinal track. This is possible because by first recording the sound program on the oblique tracks, a greater depth of penetration of magnetization of the magnetic tape is produced than takes place with the recording of video signals.
