Method for write strategy and optical recording/reproducing apparatus thereof

A write strategy method and an optical recording/reproducing apparatus using the same are provided to minimize the failure rate of write strategy design by implementing write property measurement and evaluation about all the combination of write strategy parameters. A write strategy method comprises a step of recording signal with applying constant power and initial write strategy(600), a step of obtaining the change characteristic of data signal corresponding to the change of each write strategy parameter when the recorded signal does not meet the product specifications(650), and a step of obtaining influence property according to period and interaction between the write strategy parameters by using the change characteristic of data signal and determining optimum write strategy parameters(670).
