Abstract

PURPOSE: To ensure the assured retrieving reproduction for the desired information under the compound state of the video signal and the data signal, by using the magnetic disk which has several tracks on which the video signal is recorded directly and in the analog value or the like plus the truck on which the data corresponding to the video signal mentioned above.
CONSTITUTION: The channel number of the information (map 7) to be recorded is keyed in by keyboard 20; and map 7 is photographed by TV camera 8 and then recorded on the fixed video track by magnetic head 5. Furthermore, the spot name on map 7 and the channel number are keyed in, and the spot position is indicated by light pen 38 to be recorded on the data track via magnetic head 3. When the name of the spot to be retrieved is keyed in, the coincidence is obtained between the reproduced data name code and the name code keyed in through the encoder/ decoder plus controller 22. And the reproduced video signal is mixed with the character signal at mixer 27. Thus the positions and the names on the map and the retrieving spot are reproduced on monitor TV37.
