CD labels and DVD labels are made to be used to label CDs and DVDs. A4 sheets of CD/DVD labels typically contain two circular labels (known as full face labels) and a number of rectangular labels that may be used to label the case in which each disk is stored. The circular labels are intended to cover the whole face or surface of a disk, except the center spindle hole and, in certain circumstances, the (typically transparent) components around the spindle hole, such as the clamping ring, stacking ring, and mirror band. These labels are typically used to include information about the disk's contents as well as the owner or author of that content. There are several pieces of software built expressly for this purpose.
