The optical write and reproduce device has an optical pick-up part for emitting a light signal onto an optical disk to write and reproduce data, a memory part for storing thereto at least one write strategy indicating an emission type of the light signal, and a control part for determining write strategies, such as those written on the optical disk, and controlling the optical pick-up part to emit the light signal according to the determined write strategy. The control part can select one write strategy from the group including a write strategy reproduced from the optical disk, a write strategy set for each type of optical disk, a write strategy previously tuned for a same type of optical disk, and a default write strategy. Accordingly, an optimum write strategy for a presently-mounted optical disk can be quickly determined.
