れないといった欠点があった。A magnetic disk device is known as a magnetic disk device, and this magnetic disk device uses a magnetic disk as a storage medium. On the other hand, there is a considerable amount of information used in electronic computer systems that must be kept confidential. Therefore, it is necessary to protect confidential information. To deal with this, a protection method is used for magnetic disks in which protection is performed on a volume-by-volume basis. However, this method has the disadvantage that it does not provide sufficient security and does not protect confidential information on a more detailed level, for example, on a record-by-record basis.

ついても何ら支障されることなく同一動作が行われる。The processing device 2 reads and writes information from and to the magnetic disk 7 of the magnetic disk device path 4 via the channel device 8-1 in accordance with instructions contained in the main storage device 1, and performs processing in accordance with the instructions. Password 7 along with data on this magnetic Dinuk 7
-1, and write the qualifications of the creator who wrote the data or the importance of confidentiality protection in this password.
On the other hand, this magnetic Dinuk device 4 is provided with a determining section 5, which is a feature of the present invention. When operating the magnetic disk device 4, the user inputs his/her second password from A. The magnetic disk device 4
The password is stored in the read buffer circuit 9. For example, when the processing device 2 attempts to rewrite information on the magnetic disk 7-1, the control unit 6 searches for the password 7-1 of the information to be rewritten on the magnetic disk 7, and the password content reading circuit 8 makes a read judgment. Enter in section 5. Judgment section 5
When the second password stored in the buffer circuit 9 described above is checked and the qualification or importance level of the above-mentioned content of the second password is higher or equal to that of the first password, the determination unit 5 operates the control unit 6 to rewrite the required information on the magnetic disk 7. Of course, if the determination unit 5 determines that the information is low level, that is, not eligible for use, the magnetic disk 7 is protected without being rewritten. Although rewriting has been described above, the same operation is performed for reading without any hindrance.
