CD single
A CD single is a music single in the form of a standard size compact disc, not to be confused with the Mini CD single, which uses a smaller form factor. The format was introduced in the mid-1980s, but did not gain its place in the market until the early 1990s. With the rise in digital downloads in the 2000s, sales of CD singles have decreased.The above text is a snippet from Wikipedia: CD single
