FIELD: technology and equipment for forming marks and lands by affecting working surface of optical data carrier with a ray.
SUBSTANCE: between low power level incapable of forming a mark during emission period, and recording power level, intermediate power level is inserted, value of which depends on previous land. Also proposed is heightened record power level, value of which depends on length of recorded mark.
EFFECT: decreased phase trembling.
