Method For Crystallizing Optical Data Storage Media Using Joule Heat And Apparatus Therefor

摘要

Method and apparatus are disclosed for initializing a recording film by heating it over its crystallizing temperature with Joule heat which is obtained by the current flowing on the recording film or induced thereon, the current being generated from applying electric energy to the recording film of a phase transformation typed optical disk. According to a feature of the present invention, the electric energy is provided through conductive wires being directly in contact with the recording film. According to another feature of the present invention, the recording film is heated by the induction heating technique.
