Abstract

An information recording method using an optical recording medium including 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. 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.

Claims (6)

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 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 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.
