It is not possible to duplicate multiple CD-Rs at one time. In order to solve such a problem, the applicant of the present application can duplicate the master disk in a shorter time than the conventional method, and further, can duplicate the master disk to a plurality of duplication side disks at the same time. A CD-ROM duplication device has already been proposed. Further, the conventional duplication device is a device that performs duplication operation regardless of whether or not duplication prohibition information is written in the CD-ROM, that is, if duplication prohibition information is written in the CD-ROM, it is a CD-ROM. The copy prohibition information is also written in the R, and conversely, if the copy prohibition information is not written in the CD-ROM, the copy prohibition information is not written in the CD-R either. As described above, the conventional copying apparatus has a problem that no consideration is given to the copyright in the CD-ROM. Therefore, according to the present invention, in the above-mentioned proposed CD-ROM duplicating apparatus, it is possible to further prevent illegal duplication from the CD-ROM to the CD-R, and
-CD-ROM designed to protect the copyright of ROM
It is intended to provide a duplication device.

The copy inhibition information is written in the TOC information portion of each mounted CD-R. Therefore, duplication cannot be performed based on these CD-Rs. Also, while the information is being written to the CD-R, the CD-
For example, “COPY NG DISC” indicating that the disc is a disc for which copying is prohibited is displayed for R.

On the other hand, when the selection switch 24 selects to write the duplication possibility information to the CD-R, the CD-R drives 11 and 260 provided in the master-side duplication device 100 and the slave-side duplication device 200, respectively. Duplicatable information is written in the TOC information portion of each mounted CD-R. Therefore, duplication is possible based on these CD-Rs. Also, while writing information to the CD-R, the LCD indicates that the CD-R is a disc that can be duplicated, for example, "CO".
"PY OK DISC" is displayed. Further, as described above, the copy prohibition information may be always written when the copy operation to the CD-R is performed without providing the selection switch 24.

At step 9, each of the CD-R drives 11 and 260 records the supplied data on the CD-R. In step 10, it is judged whether all the above-mentioned data recorded in the CD-ROM has been read and copied. If all the data have not been copied, the process returns to step 8. That is, when the sending of the fixed amount of data is completed and the buffer 22 can store data again, as described above, the CPU board 21 again
The data read from the CD-ROM by the CD-ROM drive 10 is stored in the buffer 22, and the buffer 2
When a fixed amount of data is stored in the CD 2, the fixed amount of data is transferred from the buffer 22 to the CD-R drive 11, 260.
