Abstract:
An information storage system in which bits of information are stored on quenched high-temperature phase magnetic film by utilizing a laser to heat the film above it''s high-temperature phase Curie point. The laser beam is attenuated to provide nondestructive readout utilizing either the magneto-optic Kerr or Faraday effects.
