The data management section disk image creation section 76 is based on the data management section disk image intermediate file 203 from the data management section disk image intermediate file creation section 74 and the data section disk image parameter information 205 from the data section disk image creation section 75. Then, a plurality of data management unit disk image information 106 corresponding to each material data management information 102 is created and output to the disk image creation unit 77. Each data management unit disk image information 106 includes one piece of material data management information 102, disk address information indicating the address thereof, and disk address information indicating the address of the material data 101 to be managed. The disk image creation unit 77 physically combines the plurality of data unit disk image information 105 from the data unit disk image creation unit 75 and the plurality of data management unit disk image information 106 from the data management unit disk image creation unit 76. By combining, the disk image 107 is created. The disk image creation unit 77 writes the created disk image 107 on a disk mounted on the disk image creation device.

The operation of the conventional disk image creating apparatus will be described below with reference to FIG. In FIG.
The data part disk image intermediate file creation part 73
A plurality of material data 1 input from the material data creation unit 71
01, the data part disk image intermediate file 202 is created, and the data part disk image creation part 75 is created.
Output to Thereafter, the data part disk image intermediate file creation part 73 creates the data part disk image intermediate file parameter information 201 based on the created data part disk image intermediate file 202 and outputs it to the data management part disk image intermediate file creation part 74. I do. Next, the data management unit disk image intermediate file creation unit 74 adds the plurality of pieces of material data management information 10 input from the material data management information creation unit 72 to the data unit disk image intermediate file parameter information 201 described above.
By adding 2, the data management unit disk image intermediate file 203 is created. The data management unit disk image intermediate file 203 roughly determines the layout of the disk image 107 actually written on the disk. Thereafter, the data management unit disk image intermediate file creation unit 74 creates the data management unit disk image intermediate file parameter information 204 based on the created data management unit disk image intermediate file 203, and outputs it to the data unit disk image creation unit 75. I do.

[0008] Subsequently, the data part disk image creation part 75 includes a data part disk image intermediate file 202.
A plurality of data part disk image information 1 equivalent to the data part of the disk image 107 based on the data management part disk image intermediate file parameter information 204;
05 is created. After that, the data section disk image creation section 75 creates the data section disk image information 1
Then, the data section disk image parameter information 205 is created based on the data section 05 and output to the data management section disk image creation section 76. Next, based on the data management unit disk image intermediate file 203 and the data unit disk image parameter information 205, the data management unit disk image creation unit 76 generates a plurality of data management unit disk image data equivalent to the data management unit of the disk image 107. The information 106 is created. Subsequently, the disk image creation unit 77 physically combines and combines the data part disk image information 105 and the data management part disk image information 106 to create a disk image 107 and write it to the disk.

[0009]
