Patent ID: 7688696

Claim:
An information recording method of recording information by irradiating an optical information recording medium with an energy beam, comprising the processes of: forming a first recording mark by the irradiation of a monopulse-shaped energy beam having at least a first power level and a second power level that is higher than said first power level; forming a space succeeding said first recording mark with a write strategy having a downward pulse of a third power level that is lower than said first power level on the backside of the midpoint of said space; and thereafter forming a second recording mark by raising said third power level to said first power level and maintaining said first power level, and raising again said first power level to said second power level and maintaining said second power level, wherein an average irradiation energy of said energy beam for forming the backside of said midpoint of said space is lower than an average irradiation energy of said energy beam for forming the front side of said midpoint of said space, and wherein there is no downward pulse inserted in the front side of said midpoint of said space, and a power level of said energy beam prior to said downward pulse is constant in forming the front side of said midpoint of said space.
