Title: (EN) METHOD AND APPARATUS FOR OPTICAL DISC WRITING
Abstract:
(EN) The present invention provides a method and apparatus for optical disc writing. The method provided by the present invention comprises steps: acquiring the writing history information of the optical disc, wherein the data storage area of the optical disc is divided into several writing areas by starting address and ending address of each writing in the history information; selecting a writing area from the plurality of writing areas for the current optical disc writing; determining the write strategy for the optical disc adopted by the current writing for writing the optical disc; and updating the writing history information of the optical disc. According to the method provided by the present invention, the appropriate area can be selected to carry out the optical disc writing, so that the life cycle shortening of the optical disc due to the over-usage of partial recording areas will be avoided, furthermore, the appropriate write strategy can be determined to improve the optical disc writing effects.FIG. 2
