magneto-optical disk
Plastic or glass disks coated with a compound (often TbFeCo) with special properties. The disk is read by bouncing a low-intensity laser off the disk. Originally the laser was infrared, but frequencies up to blue may be possible the shorter the wavelength the higher the possible density. The polarisation of the reflected light depends on the polarity of the stored magnetic field. To write, a higher-intensity laser is used to heat the material up to its Curie point, allowing its magnetisation to be altered and "frozen" as it cools. {Storage FAQ (http://www.cis.ohio-state.edu/hypertext/faq/usenet/arch-storage/part1/faq.html)}.
