By the way, in the optical disk duplicating apparatus, when the CD-ROM which is the master disk which is the copy source and the unrecorded disk are loaded, the initial check is performed immediately and the TAB of the CD-ROM is read.
LE OF CONTENTS (hereinafter referred to as TOC)
Then, the capacity of this disk is read, the capacity is read from the ATIP information in the lead-in area of the unrecorded disk, and the capacities are compared. Here, if the capacity of the unrecorded disc is small, copying cannot be performed, so the unrecorded disc was ejected without displaying anything. Therefore, there is a problem that the operator cannot determine whether the device is out of order, the disc is defective, or the disc capacity does not match. Also, since the capacity of the master disk, especially the CD-ROM, is not displayed by time in the past, the operator should use two types of the CD-R disk, that is, a 63-minute disk or a 74-minute disk. Don't know, will it be loaded and discharged for the time being? READY
There was a problem that there was no choice but to confirm whether it would be in a state. Furthermore, when a non-recorded disc such as a CD-R disc is loaded, if there is no EFM information in the TOC portion, that is, if it is a non-recorded disc, the capacity of the CD-R disc is checked from the ATIP information in the lead-in area. However, if there is EFM information at the specified location in the TOC,
In other words, if it is a recorded disc, this disc was ejected and an error was displayed. In this case, there is a problem that the operator cannot determine whether the disc is readable due to dust on the disc or the drive is out of order.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an optical disk duplicating apparatus capable of promptly performing the next operation when copying a master disk.
