JPS63200229A - Maintenance control system for memory medium - Google Patents

Abstract

PURPOSE:To omit a security control space by reading an operation memory medium in a physical unit and setting this memory medium opposite to a security control file. CONSTITUTION:A maintenance control system for memory media consists of one or more operation memory media 5, a maintenance control memory medium 6 and a restorage memory medium 10. Then a physical input part 1 is added to said control system together with a data discriminating part 2, a control data generating part 3, a physical/logical editing part 4, a security control data input part 7, a logical/physical editing part 8, and a physical output part 9. Then the information on a medium control part is delivered as the file control data on the medium 6. Then the data file control data and other data re outputted for each logical record and a trailer record is delivered after the data on the media 5 are all copied. When those data are restored, a medium control part is reproduced out of the file control data. While the file control data and other data are reproduced out of the logical records and restored.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a maintenance management system for auxiliary storage devices and auxiliary storage media in electronic computer systems.

Conventional technology Traditionally, data preservation is accomplished by copying the data to a storage medium of the same type as the data storage medium to be preserved with exactly the same content, or by copying a file on a storage medium to a file on another storage medium with the same content. I was going by that.

Problems to be Solved by the Invention However, when a storage medium is to be copied to another storage medium of the same type in the above-mentioned conventional maintenance management system, it is difficult to copy a storage medium to another storage medium of the same type. If there are a large number of storage media such as floppy disks that are used by individuals, a large amount of storage space will be required.

One way to deal with this problem is to copy the files in the storage medium to a storage medium with a larger storage capacity and store them file by file.

However, this makes it difficult to directly manage a large number of files created on a storage medium, so if a storage medium needs to be restored due to an accident such as damage to the storage medium, the relationship between the files and the storage medium cannot be maintained. It must be managed by other means, and quick recovery cannot be expected.

The present invention has been made in view of the above-mentioned conventional situation,
Therefore, it is an object of the present invention to provide a new maintenance management system for auxiliary storage devices and auxiliary storage media in computer systems, which makes it possible to solve the above-mentioned problems with the prior art. .

Means for Solving the Problems In order to achieve the above object, the "storage medium maintenance management system" of the present invention stores data on a storage medium in units of sectors or blocks, which are physical input/output units of the device. a physical input unit that inputs and outputs data; a data determining unit that searches for data on a storage medium and determines the data content; and a control data generation unit that records attribute information of the operational storage medium on a maintenance management storage medium; It is configured to include a physical logical editing section that edits physical data into logical data (records) realized by conventional technology, and a logical physical editing section that edits logical data into physical data.

When copying a storage medium for maintenance management, first
Outputs the media management section consisting of more than one piece of physical data as file control data of the storage medium for maintenance management, then outputs the data file control data and data in units of logical records, and then outputs all the data on the operational storage medium. Output a trailer record after copying. Conversely, when restoring an operational storage medium from a storage medium for maintenance management, the medium management section is reproduced from the file control data in the storage medium for maintenance management, and the file control data and data are reproduced and restored from the logical record.

EXAMPLE Below, a preferred embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention includes one or more operational storage media j, a physical input unit l that inputs physical data from the operational storage medium 3, and a physical input unit l that inputs the read data in units of physical data. and control data that generates file control data (header record) for the storage medium base for maintenance management when this data determining unit determines that it is a media management unit. Physical logical editing that writes the file control data created by the generation unit J and the control data generation unit 3 and the physical data determined by the data determination unit λ to be not a media management unit to the storage medium base for maintenance management in units of logical records. a maintenance management data input unit 7 that searches for a data file corresponding to the operational storage medium to be restored from the maintenance management storage medium 6 and reads the data, and a logical-physical edit unit that reconstructs logical data into physical data. It consists of a section t, and a physical output section t that writes the physical data reconstructed by the logical/physical editing section t of the 1 to the restoration storage medium IO.

Next, the operation of this embodiment will be explained.

2 in FIG. 1, the physical input unit l inputs the operational storage medium z (z1 to jm
), the recorded information is sequentially read and sent to the data discrimination section. The data discrimination unit identifies the media management unit that manages the entire operational storage medium and the file control data that manages files within the medium, and in the case of the media management unit, transfers the media management unit information to the control data generation unit. 3, and in the case of file control data and data, those data are sent to Hiroshi Physical and Logical Editorial Department. The control data generation section 3 converts the information in the medium management section into one piece of file control data (header record) on the maintenance management storage medium 6, and sends it to the physical and logical editing section. The physical logical editing slI sequentially outputs the data sent from the data discriminator J and the control data generator J to the maintenance management embedded storage medium 6.

Physical input section' rr! , b When the end of the operational storage medium is detected, the end detection information is output as a file trailer record onto the maintenance management storage medium 6 through the data discriminator λ, the control data generator 3, and the physical/logical editor DA.

The above operation is repeated until there are no more operational storage media to be maintained.

When restoring the storage medium, the maintenance management data input section 7
detects a file corresponding to the restoration storage medium io to be restored from the storage medium for maintenance management based on the restoration storage medium information instructed from the outside, and sends the recorded information to the logical-physical editing section g. The logical and physical editing section t restores the recording information to a medium management section, file control data, and data, and sends the restored information to the physical output section 9.

The physical output section 9 determines the sent restoration data, and in the case of a medium management section, writes it as the medium management section of the restoration storage medium 10 . The physical output unit 9 writes the data on the restoration storage medium IO as file control data in the case of file control data, and as file data on the restoration storage medium IO in the case of data.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, by reading operational storage media in physical units and associating the media with maintenance management files, maintenance management space can be reduced and management can be performed in units of media. is obtained.

In particular, storage media used by individuals, such as 7-arithm disks and IC cards, are more effective.
