A Magneto-optical disc and the numerous rectangles on its surface.
A magneto-optical drive is a kind of optical discdrive capable of writing and rewriting data upon a magneto-optical disc.
Magneto-optical drives should not be confused with Floptical drives, which likewise combine ferromagnetic and optical technologies, albeit in a different manner.
In computing, sound reproduction, and video, an optical disc is flat, circular, usually polycarbonate disc whereon data is stored in the form of pits (or bumps) within a flat surface.
This data is generally accessed when a special material on the disc (often aluminum) is illuminated with a laser diode.
The information on an optical disc is stored sequentially on a continuous spiral track from the innermost track to the outermost track.
