Abstract
An optical disc device measures lengths of each mark and each land recorded using a reference write strategy and an alternative write strategy in which at least one parameter is varied in two or more combinations of marks and lands. A deviation value of each of the marks and lands is computed by shifting the write strategy on the basis of the lengths. Inherent contractile rates of all marks and lands are computed from the computed deviation value and the probability of occurrence of each of the marks and lands. A variance of the deviations by the combination of each of the marks and lands is computed from the computed deviation value. The write strategy is set using the computed inherent contractile rates such that the computed variance is minimized.
