ABSTRACT:
An information recording method including irradiating an optical information recording medium containing a phase change recording layer on a substrate having a guide groove with continuous light of a laser beam having an erase power level Pe to determine a transition linear velocity Vo defined as a minimum linear velocity above which the following relationship is satisfied: Rr=Ra/Rb<1, wherein Rr represents a reflection light intensity ratio, and Ra and Rb represent a reflection light intensity measured after and before the irradiation of the optical information recording medium with the continuous light, respectively, prior to recording information in the optical information recording medium.
