MO Technology
Definition: Magneto-Optical Technology: a rewritable optical storage technology that uses a combination of magnetic and optical methods. Data is written on an MO disk by both a laser and a magnet. The laser heats the bit to the Curie point, which is the temperature at which molecules can be realigned when subjected to a magnetic field. A magnet then changes the bit's polarity. Writing takes two passes. Unlike with phase-change drives MO disks do not have to be "reformatted" when full. See also LIMDOW.
