The term CD5 designates the standard 120-millimeter compact disc, differentiating it from the smaller 80-millimeter CD3 format. It provides the standard capacity of 74 to 80 minutes of audio or up to 700 megabytes of digital data. The physical dimensions dictate the standard tray size and laser tracking limits in optical drives.

Insider tip
The designation is primarily used when distinguishing the standard disc size from smaller mini-CD formats in manufacturing and packaging.
