What is CD diskette?

A diskette, or "floppy disk", is a small, removable magnetic disk. The earliest models had a diameter of 8 inches and a capacity of less than 200 kilobytes. The diskette is still in use today, using a physical format pioneered by Apple, with a standard capacity of 1.44 megabytes. A CD, or "compact disc", is a small, removable optical disc, with a capacity of around 800 megabytes. Originally they were a write-once technology, but rewriteable discs are now available.
