Zusammenfassung:	PROBLEM TO BE SOLVED: To read and provide map data required by a navigation system from a recording medium, even if the processing program at the navigation system is C or JAVA language. SOLUTION: On a recording medium 20, data reading procedure of map data 22 are previously recorded at a method part 24. A data access part 14 reads desired data from the method part 24 in a procedure (program) read from the method part 24 according to a request API when a navigating function part 12 requests map data. The read data are fed to the navigating function part 12 as a byte array object.
