Patent ID: 7349317

Claim:
An information recording method using an optical recording medium comprising the steps of: forming a plurality of recording pulses including information to be recorded to irradiate the optical recording medium; and recording the information to the optical recording medium by irradiating the plurality of recording pulses on the optical recording medium; wherein at least one of a leading edge of a first recording pulse of the plurality of recording pulses and a trailing edge of a last recording pulse of the recording pulses shifts at a shifting value; and wherein the shifting value 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 for the leading edge of the first recording pulse of the plurality of recording pulses or a combination of the length M(n) of the mark within one of the plurality of recording pulses being currently written and a length S(n+1) of a space subsequent to the mark for the trailing edge of the last recording pulse of the plurality of recording pulses.
