magneto-optical recording


General Science


  • noun a method of recording that uses an optical disc covered with a thin layer of magnetic film that is heated by a laser. The particles are then polarised by a weak magnetic field.


  • A high-capacity disc technology which utilizes both optics and magnetism to write, read, and rewrite data. A laser is first utilized to heat the recordable portions on the disc to the magnetic transition temperature, and then the bits are aligned magnetically. A laser is used for subsequent reading, and such discs are usually available either in a 3.5 inch or 5.25 inch diameter format. Also spelled magneto-optic recording.
