摘要 |
<p>An optical recording medium comprises a transparent substrate (103), an inner protection layer (104), a recording material layer (105), an outer protection layer (106), and a reflection layer (107), which are laminated in this order. In an in-groove recording mode, the ratio of the thickness of the recording material layer (105) to the thickness of the outer protection layer (106) is in a range between 0.52 and 0.95. In an on-land recording mode, the ratio of the thickness of the recording material layer (105) to the thickness of the outer protection layer (106) is in a range between 0.32 and 0.6. <IMAGE></p> |
