Patent ID: 7660218

Claim:
An optical recording method in which an optical recording apparatus records information on a recording medium having a plurality of layers comprising at least one recording layer and another recording layer by irradiating a laser beam to the recording medium, the optical recording apparatus extracts an irradiation condition of the laser beam by recording and reproducing test information with respect to a test area of the recording layers and records the information on the recording medium by irradiating the laser beam to the recording medium by the use of the extracted irradiation condition, the method comprising: recording and reproducing the test information with respect to the one recording layer with a gradual variation in recording condition of laser power and a gradual variation in recording condition of pulse-width; extracting the irradiation condition suitable for recording information on the one recording layer on the basis of a test result of a reference recording layer testing step; recording and reproducing the test information with respect to the another recording layer with the gradual variation in recording condition; wherein only one of the laser power and the pulse-width are varied; and extracting the irradiation condition suitable for recording information on the another recording layer on the basis of the test result of the reference recording layer testing step and a test result of an another recording layer testing step.
