摘要 |
At least a first recording layer (L0 layer) and a second recording layer (L1 layer) are provided. In the first recording layer, a first recording track path (a groove: a guiding groove) is formed for recording recording information. The second recording layer is arranged on the first recording layer and has a second recording track path (a groove: a guiding groove) formed in an opposite direction to the first recording track path for recording recording information. On an edge part on one side of the second recording layer, a first buffer area ( 103 - 1 ) is previously formed as a pre-recording area by an embossed pit (in the case of DVD-RW) or by a pit formed by recording laser irradiation (in the case of DVD-R).
