Abstract

PURPOSE:To realize an auxiliary storage device artificially by discriminating in-use software without reference to the storage format of the auxiliary storage device, by accessing the auxiliary storage device differing in access format by using an in-use program. CONSTITUTION:Even when user software 3 aims at an N-bit sector, specifies a sector address on an auxiliary storage device 1, and sends a request to access specific storage contents, the conversion program 5 of an auxiliary storage device virtual system converts the sector address, specified by the user software 3, into a sector address on the auxiliary storage device for M-bit sectors and perform reading to and writing from a auxiliary storage device 2, thereby artificially placing the storage contents of the auxiliary storage device 1 in the auxiliary storage device 2.
