Duplicating a CD typically requires two steps: ripping content from the first disc and burning that content to the second disc. On a Windows computer, start by inserting the original disc into the CD drive. Navigate to the disk in File Explorer, right click, and select open. Copy the contents of the disc to your computer, then insert the blank disc into your drive. Move the copied contents over to the blank disc. Finally, right click, and select Burn.
On Mac OSX, the same effect is accomplished using Disk Utility. Start by inserting the original disc into your drive. Open Disk Utility, which is located in the Utilities folder in Launchpad. Select the original disc, and click Restore. Drag the disc you wish to copy to the Source field and the blank disc to the Destination field. Finally, click the Restore button.
Many applications make duplicating a CD even easier. Music programs such as iTunes or Windows Media Player allow you to rip music easily from a disc to the hard drive. Some also allow you to burn music CDs. Other applications offer disc duplication features. For example, Nero has a function to copy any entire disc quickly to either a virtual image on the hard drive or to another disc.
