A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. 130 mm (5.25 in) and 90 mm (3.5 in) discs are the most common sizes. In 1983, just a year after the introduction of the compact disc , Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable ...
MD Data is a type of magneto-optical medium derived from MiniDisc. [ 1 ] In developing and marketing it, Sony was trying to set the new standard for removable media to replace the 3½-inch diskette it had also helped create.
A magneto-optic effect is any one of a number of phenomena in which an electromagnetic wave propagates through a medium that has been altered by the presence of a quasistatic magnetic field. In such a medium, which is also called gyrotropic or gyromagnetic , left- and right-rotating elliptical polarizations can propagate at different speeds ...
Magneto-optical disc storage is optical disc storage where the magnetic state on a ferromagnetic surface stores information. The information is read optically and written by combining magnetic and optical methods. Magneto-optical disc storage is non-volatile, sequential access, slow write, fast read storage used for tertiary and off-line storage.

The 64DD [a] is a magnetic floppy disk drive peripheral for the Nintendo 64 game console developed by Nintendo.It was announced in 1995, prior to the Nintendo 64's 1996 launch, and after numerous delays was released in Japan on December 11, 1999.
Magneto-optical (MO) drives were introduced in 1985. MO discs are written using a laser and an electromagnet. The laser would heat the platter above its Curie temperature at which point the electromagnet would orient that bit as a 1 or 0. To read, the laser is operated at a lower intensity, and emits polarized light.
