FIELD: engineering of devices for recording data onto optical data carriers.
SUBSTANCE: device for recording data on optical record carrier contains generator of recording signal shape for generation of recording signal shape, having erasing template, which contains multi-impulse signal, having high level, which is greater, than level of erasing power, and having low level, which is lower, than level of erasing power, and reading block, which irradiates optical record carrier with light depending on generated recording signal shape for forming a mark or a gap.
EFFECT: prevented distortion of mark shape during recording.
