摘要: Because conditions for recording identification data of a medium vary in accordance with the structure different media, such as single-layer or multiple-layer structure, stable has been difficult task. To solve this problem, an incident side laser beam on optical disk 5 and double-layer 6 is opposite substrate 1 upon which user recorded. From even 6, not affected by layer second 12 b like. Therefore, can be recorded under same 5.
