The CD-MO standard allowed for an optional non-erasable zone on the disc that could be read by CD-ROM units. Data recording (and erasing) was achieved by heating the magneto-optical layer's material (e.g. Dy Fe Co or less often Tb Fe Co or Gd Fe Co ) to its Curie point and then using a magnetic field to write the new data, in a manner ...
