ABSTRACT:
An optical disc apparatus for recording synchronous information and data on an optical disc. The synchronous information recorded at the beginning of a frame is established to a mark in one frame in a plurality of frames. For example, the synchronous information of the mark and the synchronous information of a space are alternately established. In a frame, the synchronous information of the mark may be established, and in the subsequent frame, either the synchronous information of the mark or the synchronous information of the space may be selected so as to allow a DSV to be minimized. On the synchronous information of the mark, ROPC is executed for adjusting power of laser light.
