ABSTRACT:
When writing user data D, the user data D is stored in a register 46, and using both the user data D and the sector information (ID) of the user data D, an error correction code ECC is generated by an ECC generation algorithm Ar. A stored information Rw made up of the user data D and the generated ECC is written on a disk. In the reading, the user data Dr of a read record Rr is temporarily stored in the register 46, and an ECC check algorithm is executed. This ECC check is executed for combined data of the user data Dr and its position information. When any error is found in the position information portion in the combined data, the user data is determined that the read user data is wrongly addressed. When an error is found in the user data Dr portion, the user data is corrected by ECC and the corrected user data is output.
