  • Method for laser recording utilizing dynamic preheating
    Patent number: 4383261
    Abstract: An improved method and apparatus for laser recording of information onto a metal film by dynamically heating the film immediately prior to recording. A single track of information is recorded by directing two laser beams onto the film. An unmodulated preheat beam supplies energy to raise the temperature of the metal film to just below that required for recording. A modulated write beam then provides sufficient additional energy to selectively raise the temperature of the film to a necessary level for recording of data.
