An apparatus for recording data on an optical recording medium comprising a laser beam source 51 for emitting a laser beam, an objective lens, laser power control means 52 for modulating a power of the laser beam emitted from the laser beam source like a pulse between at least a recording power and a base power having a lower level than the recording power, a memory 55 , and a control unit 50 for controlling a whole operation, wherein a timing for causing the power of the laser beam to rise to be the recording power when forming a longer recording mark than the shortest recording mark on a recording layer of the optical recording medium by using a laser beam modulated by a single pulse is delayed from a timing for causing the power of the laser beam to rise to be the recording power when forming the shortest recording mark and the control unit can build a recording strategy determined to form a recording mark on the recording layer based on ID data recorded on the optical recording medium stored in the memory. |
