Patent ID: 7746742

Claim:
An optical disc recording method comprising the steps of: obtaining information which is necessary for finding optimum recording power of a laser; recording, on a trial writing area of an optical disc medium, a data pattern for power correction while changing stepwise recording power according to the information thus obtained; calculating a modulation in response to the recording power by using a readout signal obtained by reading out the data pattern; determining first recording power using the modulation in response to the recording power; measuring an ambient temperature of the optical disc medium; finding multiplication coefficients depending on the ambient temperature; and finding the optimum recording power by multiplying the first recording power by at least one of the multiplication coefficients thus found; wherein the first recording power is recording power threshold Pthr; wherein the optimum recording power Popt is found by using an equation, Popt=ρ×κ×Pthr, where ρ and κ denote the multiplication coefficients; and wherein at least one of the multiplication coefficients ρ and κ is temperature-dependent.
