PROBLEM TO BE SOLVED: To flexibly share partially different disc devices in a lower level of an operating system when the disc devices in multiple computers are shared. SOLUTION: A disc sharing part 114 constructed of a READ routine 115 and a WRITE routine 116 is arranged between a file system processing part 113 and a disc driver processing part 117 inside an operation system 112. The WRITE routine 116 converts writing to a common disc device 120 into that to a specific disc device 130 and stores update information in a specific table 132 inside the specific disc device. The READ routine 115 properly converts reading from the common disc device 120 into reading from the common disc device 130 or the specific device 130 by referring to the specific table 132 in the specific disc device 130.
