The term burn is used to describe the action of creating a CD or other recordable disc. You can identify a burned or recordable disc by looking at the bottom of the disc. Recordable discs like those shown in the picture to the right have a green or purple tint to them.
What type of disc can be burned?
Any blank disc or recordable disc can be used in a burner to create a new disc or copy an existing disc. Keep in mind that a standard disc and a closed disc cannot have information burned to the disc.
