Patent ID: 7764583

Claim:
An information recording method of recording information by irradiating an optical information recording medium having multilayered recording films with an energy beam, wherein: when information is recorded on a first recording layer disposed on the side of the incidence of said energy beam, said information recording method comprises 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 only on the backside of the midpoint of said space, a falling edge and a rising edge of said downward pulse being on the backside of said midpoint, 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; and when information is recorded on a second recording layer farthest from the side of the incidence of said energy beam, a write strategy different from said write strategy is used.
