Patent ID: 7599265

Claim:
A recording method for recording information onto an optical recording medium with a recording condition determined based on a result of test recording carried out by irradiating pulsed laser beams onto the medium wherein the test recording is carried out by changing one or both of the power and pulse width of the laser beams in a stepwise manner, and a range of changing the power, pulse width, or both is determined based on a result of checking recording characteristics prior to the test recording, wherein the recording characteristics are checked by carrying out test recording on the optical recording medium by a plurality of predetermined reference conditions and detecting a result of reproduced characteristics, wherein the range of changing the power is determined based on a difference between a larger power value and a smaller power value at two points that satisfy a reproducing criterion, the larger and smaller power values being derived based on results of approximating the recording characteristics of the optical recording medium using a plurality of reproduced values obtained by detecting the reproducing characteristics.
