Magnetic recording disk

Information is recorded on a floppy disk in a state in which the confidentiality of the information is maintained. An ID signal representing ID information is magnetically recorded down to the lower layer of a floppy disk when data is recorded. A data signal representing information (a data file) to be recorded is also magnetically recorded down to the lower layer of the floppy disk. A security signal is magnetically recorded on the upper layer of the floppy disk over at least the data signal that has been recorded on the lower layer of the floppy disk. At the time of data reproduction, the ID signal is reproduced from the floppy disk and the ID information represented by the reproduced ID signal is compared with entered ID information. When the two items of compared ID information agree, the security signal that has been recorded on the upper layer of the floppy disk is erased. The data signal that has been recorded on the lower layer of the floppy disk is then reproduced.
