Information recording method, information recording medium and information recording apparatus
View Patent ↗An information recording apparatus using an optical recording medium includes a light source to irradiate a light beam to the optical recording medium and a pulse former for forming a plurality of recording pulses of the light beam. A leading edge of a first recording pulse of the recording pulses shifts at a shifting value, and the shifting value is determined by a combination of a length of M(n) of a mark being currently written and a length s(n−1) of a space precedent to the mark.
1. An information recording apparatus using an optical recording medium comprising:
a light source to irradiate a light beam to the optical recording medium; and
means for forming a plurality of recording pulses of the light beam including information to be recorded;
wherein a leading edge of a first recording pulse of the plurality of recording pulses shifts at a shifting value; and
wherein the shifting value of the leading edge of the first recording pulse of the plurality of recording pulses is determined by a combination of a length of M(n) of a mark within one of the plurality of recording pulses being currently written and a length S(n−1) of a space precedent to the mark.
2. An information recording apparatus according to claim 1 , wherein the shifting value has been stored in advance within the optical recording medium in a lookup table storing information on the shifting value.
