Patent ID: 6925043

Claim:
An optical recording apparatus comprising: a light source for generating a light spot used for information recording; detection means of detecting an aberration amount of the light spot as an aberration detection signal S or detecting a signal associated with the aberration amount, as an aberration detection signal S; and control means of controlling an output of the light source by use of the detected aberration amount or the detected associated signal; wherein said control means controls the output of the light source so that the output of the light source for recording is P 0 /(1−K·S 2 ) where K is a predetermined constant and P 0 is the light source output for recording on condition that there is no aberration, or said control means controls the output of the light source so that the output of the light source for recording is Pi(1−K·Si 2 )/(1−K·S 2 ) where K is a predetermined constant and Pi is the light source output for recording on condition that Si is obtained as the aberration detection signal, said Pi and Si are obtained by initial learning when the recording operation is performed.
