Abstract
In order to provide an optical recording condition setting method which reduces effects from uneven properties of a rewritable or recordable optical disk and an optical recording/reproducing device, and to provide an optical recording/reproducing device which executes the method, (i) a test writing is carried out with respect to an optical disk under various settings of recording-power parameters for use in forming a shortest record-mark (S1 to S3), (iii) a test pattern used in the test writing is reproduced (S4), and then (iv) recording-power parameters that result in a good quality of reproduced signals are selected (S5).
