PROBLEM TO BE SOLVED: To eliminate verification processing during write by lowering an uncorrectable error occurrence probability during the read-out of data from a disk unit. SOLUTION: This disk read/write control program manages prescribed n-piece of data sector in one group as a unit (sector) of prescribed L-byte of data, and makes a computer carry out the write and read of a storage medium. This program makes the computer function as a parity generating means which forms m-piece of parity sector consisting of L-byte by repeating processing to generate m-byte of error detection correction code to n-byte of data formed by extracting 1 byte from the data sector of the same group for all L-byte of data, and a read/write control means which distributes the n-piece of data sector of the same group and the corresponding m-piece of parity sector as one parity group and writes them into the storage medium so that sectors belonging to the same parity group are not adjoined with each other.
