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 ...
Optical - Optical recording heads use the principles of optics and light to impart energy on a recording medium, which accepts the energy in a readable manner, e.g. by melting or photography. Note that Magneto-optical recording, though using optics and heat , should properly be considered a magnetic process, since the data stored on magneto ...

WORM drives preceded the invention of the CD-R, DVD-R and BD-R.An example was the IBM 3363. [1] These drives typically used either a 5.1 in (13 cm) or a 12 in (30 cm) disc in a cartridge, with an ablative optical layer that could be written to only once, and were often used in places like libraries that needed to store large amounts of data.
