ABSTRACT:
Apparatus and process for writing information using a laser light writing beam focused on a light sensitive layer having a threshold power level above which the layer reacts to the laser write beam. The intensity of the writing beam is adjusted relative to the threshold power level. In one embodiment, the peak intensity of the writing beam is adjusted so that one-half of the peak intensity is equal to the threshold power level. In a second embodiment, the average intensity of the writing beam is adjusted to equal the threshold power level.
