Duplicate the files on the CD to the Mac, then burn the dupe files on a blank CD.
Here's
an instruction page.
However, with OS 9, burning a disk using the Mac instead of some other app also burns a list of your desktop files (including any sensitive file names — though not the files) that anyone and everyone who runs the CD in a computer can see.
The article at
this link explains the problem, and suggests the freebie TechTool Lite to rebuild your desktop and kill the list. But TechTool Lite copies then puts back any comments you may have made in the files' Get Infos. So erase any comments you don't want made public before running TechTool Lite's desktop rebuild.
Or find and download the free System 9 extension Total Desktop Rebuild, then restart the machine and rebuild the desktop the normal way. Total Desktop Rebuild erases the comments.
Whether you use TechTool Lite or Total Desktop Rebuild, the new desktop files will be burned, as well, and will still reveal all the applications you have loaded in the machine.
