Information recording method, information recording medium and information recording apparatus
View Patent ↗An information recording method using an optical recording medium includes the steps of forming a plurality of recording pulses to irradiate the optical recording medium and recording information to the optical recording medium by irradiating the recording pulses on the optical recording medium. At least a leading edge of a first recording pulse and a trailing edge of a last recording pulse of the recording pulses shift at a shifting value, wherein the shifting value is determined by combinations of a length of M(n) of a mark being currently written and at least one of a length s(n−1) of a space precedent to the mark and a length s(n+1) of a space subsequent to the mark.
1. 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.
2. An information recording method 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.
