Patent ID: 7684302

Claim:
In an optical information recording device that records information onto an optical recording medium by irradiating a laser beam based on a recording pulse corresponding to each of multiple types of codes, the recording pulse comprising a top pulse, an intermediate pulse, and a last pulse, a method of setting a recording condition, comprising: configuring a reference condition for the recording pulse; configuring a condition for the last pulse after configuring the reference condition; and configuring a condition for the intermediate pulse after configuring the last pulse, wherein the condition for the last pulse is determined based on a positional relationship between the amplitude of a signal obtained by reproducing the shortest code and that obtained by reproducing the second shortest code, and the condition for the intermediate pulse is determined based on a positional relationship between the amplitude of a signal obtained by reproducing the shortest code and that obtained by reproducing a code of which the amplitude of a reproduction signal is comparable to that of a longest code.
