PURPOSE:To provide a method of improving recording density on a high density information recording medium and in a recording device using the former. CONSTITUTION:This method is achieved by classifying by colors and configurations input data read by an optical data reader device 2 from an input paper surface 1 and classifying them by contour lines for map data, and recording classified data on a recording medium on a processed substrate 6 such that they are different in heights on the foregoing recording medium Hereby, information is recorded with higher capacity and a reference analysis is facilitated. Particularly, for map information high accuracy greater capacity information recording is ensured. |
