FIELD: optical data carriers.
SUBSTANCE: in accordance to method, recording signal is generated, template for erasing which has predetermined pulse signal, high level of which is higher than erasing power level, and low level of which is lower than erasing power level. In variants, power level of first pulse of erasing template is low level of erasing template, and power level of last pulse of erasing template is high level, or power level of first pulse of erasing template is low level of erasing template, and power level of last pulse of erasing template is low level, or power level of first pulse of erasing template is high level of erasing template, and power level of last pulse of erasing template is high level, or power level of first pulse of erasing template is high level of erasing template, and power level of last pulse of erasing template is low level.
EFFECT: prevented distortion of mark shape, improved recording/reproduction characteristics.
