The present invention provides a recording method for a phase-change
optical recording medium. The recording method of the present invention
contains the step of irradiating an electromagnetic wave having a
multipulse pattern so as to perform recording on a phase-change optical
recording medium containing a phase-change recording layer. This method
is characterised in that a starting time of a front pulse of the
multipulse pattern delays 0.5T to 1.25T from a starting point of the
first reference clock relative to the recording mark, where T is a
reference clock of the multipulse pattern.
