OPTICAL DATA WRITE/REPRODUCE DEVICE FOR DETERMINING OPTIMUM WRITE STRATEGY AND WRITING DATA ACCORDING TO OPTIMUM WRITE STRATEGY, AND, METHOD THEREOF

摘要

An optical write and reproduce device is provided to determine an optimum write strategy from a broader selection of choices. 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.
