Abstract
PURPOSE:To easily correct the contents of a magnetic recording part when an error is present, by recording up-to-date data and old data together in the magnetic recording part. CONSTITUTION:The contents of the magnetic recording part 1 of a magnetic card 6 are read or written by a read/write device 6. In a read data buffer 19, the read contents are stored as they are and in a written data buffer 20, data to be written are stored. To the up-to-date area of a read/write explosion area 18, the contents of the up-to-date data recording area 2 of the magnetic recording part 1 are transferred from the buffer 19, and to the old data storage area, the contents of the old data recording area 3 are transferred. During writing operation, the contents of the up-to-date and old data storage areas are written in the magnetic recording part 1 through said buffer 20. The contents are updated or erased by an application program processing part 9. In the magnetic recording part 1, the up-to-date and old data are recorded, so an error is corrected easily.
