Patent ID: 7268795

Claim:
A method for recording graphic image data on a recording medium using an electromagnetic radiation beam to induce a change in an energy level of the recording medium, thereby providing a chemical reaction in light sensitive materials on the medium to form an image, comprising: (a) applying the electromagnetic radiation beam to the recording medium in a first power profile; (b) maintaining the first power profile at or below a first power level until a first energy level of the recording medium is reached wherein an energized state of the recording medium provides the chemical reaction sufficient to form the image; (c) changing the electromagnetic radiation beam power to a second power profile having an average power level sufficient to keep the energy level of the recording medium below a second energy level at which substantial ablation or disintegration of the recording medium occurs; and (d) maintaining the second power profile at or below a second power level to keep the energy level of the recording medium above the first energy level and below the second energy level.
