PURPOSE:To detect an error in the write information, by comparing the code inversely converted information and the write information, when the code converted information is written in the magnetic disk apparatus. CONSTITUTION:When the bit parallel write information (a) is provided to the parallel-series conversion part 1 of the magnetic disk control unit, the series write information (b) is provided to the information code conversion part 2 of the magnetic disk apparatus, it is converted to a write code (c), and as soon as it is written, it is provided to the read information conversion part 3 through the code selective part 5. Subsequently, the code inversely converted information (e) is input to the information comparation part 7, the write information (b) is compared with the delay write information (g) which has been delayed by the delay part 6, and as a result, when an error detection signal (h) is output, it is detected to have been written erroneously in the magnetic disk. |
